DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below. FIG. 1 is a schematic diagram showing a first preferred embodiment of the present invention. FIG. 1 shows a full-color image forming apparatus. Components substantially the same as those in the conventional image forming apparatus shown in FIG. 9 are denoted by the same reference numerals.

This full-color image forming apparatus includes a toner image forming means 17, an intermediate transfer member 3, a pressing roller 4, a heating roller 5, a tension roller 6, a pressure roller 7, a roller-shaped cleaning member 11, and a cooling fan 13. Provided. The toner image forming means 17 has four built-in developing units for each color of yellow, magenta, sian, and black, and forms a color toner image according to image information. Each developing unit includes a charger, an exposure unit, and a developing unit (not shown).

The endless belt-shaped intermediate transfer member 3 is stretched by a heating roller 5 and a tension roller 6, and receives and transfers the toner image at a first transfer position T1 while circulating in the direction of arrow B. The toner image is transported to the second transfer position T2. The transfer material guide 9 supplies the transfer material 8 to the second transfer position T2.

The heating roller 5 and the pressure roller 7 disposed opposite to each other are heated at the second transfer position T2 in a state where the intermediate transfer body 3 and the material to be transferred 8 are overlapped with the toner image therebetween. The heating and pressurizing means for pressurizing while pressing is constituted. The heating roller 5 has a three-layer structure of a base material, an intermediate layer, and a surface layer. The base material is made of metal, the intermediate layer is made of silicone rubber, and the surface layer is made of viton (fluorine rubber: manufactured by DuPont). Is used. The transferred material 8 after the heating and the pressurization by the heating and pressurizing means are released, the intermediate transfer body 3
And four color toner images are obtained.

In this embodiment, a cleaning member 11 is disposed opposite the pressure roller 5 with the intermediate transfer member 3 interposed therebetween, and between the photosensitive drum 1 and the pressure roller 7. The cleaning member 11 includes a roller-shaped metal base material and a surface layer.

This surface layer is formed from a resin composition mainly composed of a resin having a glass transition point lower than the melting point of the binder constituting the toner or a resin having a glass transition point lower than the melting point of the binder constituting the toner. ing.

In the case of a resin whose main component is a resin having a glass transition point lower than the melting point of the binder constituting the toner,
As a main component, a resin having a glass transition point lower than the melting point of the binder constituting the toner, and a resin having a glass transition point equal to or higher than the melting point of the binder constituting the toner as other components are preferable, but the cleaning effect is more improved. In order to exert the effect, the ratio of the resin having a glass transition point lower than the melting point of the binder constituting the toner in the surface layer of the cleaning member is preferably as high as possible, and can be selected according to the target value in cleaning.

Therefore, the resin constituting the surface layer of the cleaning member is relatively determined in relation to the binder constituting the toner, and can be arbitrarily selected depending on the binder constituting the toner. The surface of the cleaning member is formed, for example, by the above-described method of applying the resin or the resin composition. During cleaning, the surface of the cleaning member is controlled to a temperature equal to or higher than the glass transition point of the resin constituting the surface layer of the cleaning member.

By this temperature control, the adhesiveness of the resin constituting the surface layer of the cleaning member is imparted, and the adhered matter including the toner residue on the intermediate transfer member is moved to the cleaning member by the adhesiveness. In this case, if the surface of the cleaning member is controlled to a temperature equal to or lower than the melting point of the resin constituting the surface layer of the cleaning member and equal to or higher than the glass transition point, the resin does not melt, has tackiness, and the cleaning effect is improved. Become a target.

When deposits containing toner residue are deposited on the surface of the cleaning member by cleaning,
The next cleaning can be performed by controlling the surface temperature of the cleaning member to remove the deposit including the toner residue from the cleaning member.

If the thickness of the resin constituting the surface layer of the cleaning member is too small, the surface layer may be removed from the cleaning member when pressure is applied to the surface layer of the cleaning member. It may be deformed by heating, and the contact between the surface layer of the cleaning member and the intermediate transfer member may be insufficient. Therefore, the thickness of the resin constituting the surface layer of the cleaning member is 1 to 100 μm, preferably 20 to 30 μm. Further, the surface layer of the cleaning member is not limited to a sheet shape, and may be formed of a nonwoven fabric or the like.

As the resin constituting the surface layer of the cleaning member, for example, a polyester resin having a melting point of 110 ° C. and a glass transition point of 60 ° C., and a polyester resin having a melting point of 120 ° C. and a glass transition point of 70 ° C. are preferable. A simple example. Hereinafter, the same applies to the surface layer of the cleaning member in each of the embodiments described later.

The surface of the cleaning member 11 is air-cooled by the cooling fan 13. When the cooling fan 13 is provided, the surface of the cleaning member 11 is cooled by the cooling fan 13 before the adhesive strength of the surface of the cleaning member 11 decreases due to a continuous cleaning cycle, and the surface of the cleaning member 11 is maintained at a predetermined temperature. Temperature can be controlled.

The cleaning member 11 comes into contact with the intermediate transfer member 3 only during a cleaning cycle, and is separated in the R direction during other image output and the like.

Next, another embodiment of the image forming apparatus of the present invention will be described. FIG. 2 is an outline showing a second embodiment of the image forming apparatus of the present invention. FIG. 2 illustrates a full-color image forming apparatus according to a second embodiment.
This full-color image forming apparatus has a first embodiment (
Unlike FIG. 1, the cleaning member 11 is disposed between the heating roller 5 and the pressure roller 7 and the tension roller 6 with the metal cleaning member 11 facing the opposing roller 18 with the intermediate transfer member 3 interposed therebetween. ing. Further, both the pressure roller 7 and the cleaning member 11 have a separating mechanism in the R direction with respect to the intermediate transfer body 3. During image output, the pressure roller 7 is pressed against the intermediate transfer member 3 and the cleaning member 11 is separated. Conversely, during the cleaning cycle, the cleaning member 11 is pressed against the intermediate transfer body 3, and
The pressure roller 7 is separated. Thus, surface contamination of the pressure roller 7 by the toner can be prevented.

FIG. 3 shows the structure of the cleaning member 11 according to the second embodiment. Rolled metal substrate 14
Above, thickness = 2mm, hardness = 3 for elasticity and heat insulation
A foamed silicone rubber layer 15 of 0 Hs was disposed, and a resin sheet 16 was disposed thereon. On the resin sheet, for example,
A polyester resin having a melting point of 120 ° C. and a glass transition point of 70 ° C. is applied. By providing the silicone rubber layer, the surface of the cleaning member 11 can easily come into contact with the surface of the intermediate transfer member 3 even when the toner unevenness on the intermediate transfer member is large, and the temperature rise of the entire cleaning member 11 is suppressed. Therefore, the cleaning according to the present invention can be performed without using a cooling device.

Next, still another embodiment of the image forming apparatus of the present invention will be described. FIG. 4 is a schematic diagram showing a third embodiment of the image forming apparatus of the present invention. FIG. 4 shows a full-color image forming apparatus according to a third embodiment, which differs from the first embodiment (see FIG. 1) in that the cleaning member 11 has an endless belt shape. The tension roller 6 is stretched by two cleaning member suspension rollers 12, faces the tension roller 6 with the intermediate transfer member 3 interposed therebetween, and is disposed between the pressure roller 7 and the photosensitive drum 1. The tension roller 6 has a heating device inside, and heats the intermediate transfer body 3 via the tension roller 6 only during a cleaning cycle.

The cleaning member suspension roller 12 is a metal roller having a silicone rubber elastic layer on its surface. The toner image forming means 2, the pressing roller 4, and the pressing roller 7
The cleaning member 11 and the intermediate transfer member 3
It has a separation mechanism in the R direction. At the time of image output, the toner image forming means 2, the pressing roller 4, and the pressing roller 7
, And the cleaning member 11 is separated.
Conversely, during the cleaning cycle, the cleaning member 11
Is pressed against the intermediate transfer member 3, and the toner image forming means 2, the pressing roller 4, and the pressing roller 7 are separated from each other. Thus, it is possible to prevent the image forming apparatus 2 from being damaged by the heat of the intermediate transfer member 3 heated by the tension roller 6 and to prevent the surface of the pressure roller 7 from being stained by the toner. The cleaning member 11 has, for example, a two-layer structure in which a polyester resin having a melting point of 110 ° C. and a glass transition point of 60 ° C. is applied on a polyimide substrate having a thickness of 75 μm.

In this embodiment, a configuration as shown in FIG. 5 is also possible. In this case, the cleaning member 11
It is stretched by three cleaning member suspension rollers 12, and only the two cleaning member suspension rollers 12 on both sides come into contact with the intermediate transfer member 3. The cleaning member suspension roller 12 is a metal roller having a silicone rubber elastic layer on the surface. Further, the cleaning member 11 has a separating mechanism in the R direction with respect to the intermediate transfer body 3. In this case, the number of times that the cleaning member 11 contacts the intermediate transfer member 3 is 2
Since the number of cleaning operations is increased, it is possible to perform better cleaning.
