１ｖｃ放電か発生する。Flash fixing is a method in which the flash energy of a flash lamp is instantly absorbed by the toner on the recording paper, raising the temperature of the toner itself above its melting point and fixing it on the recording paper.
The flash lamp part of the flash fixing device is usually
As shown in FIG. 3, a flash lamp 1 such as a xenon lamp is covered with a reflective member 2, and the flash light emitted by the flash lamp 1 is irradiated onto a recording paper P through a heat-resistant transparent glass 3, so that the recording paper P is set at 5 VC. Discharge electrodes 4 are provided at opposite ends of the interior of the flash lamp l, and these m poles 4 are connected to a charging/discharging circuit of a power supply device via terminals 51+52, respectively, and are connected to a capacitor in the circuit. In order to generate a flash by releasing the stored electrical energy, the charging voltage of the capacitor must be a high voltage ranging from several tens of volts to several thousand volts in order to obtain sufficient flash energy. The flood lamp 1 is provided with a trigger 6 in addition to the discharge lamp 4.
The trigger electrode 6 is connected to the trigger circuit of the power supply device through the terminal 7, and when a high voltage trigger pulse voltage is applied to the trigger electrode 6 by the trigger circuit, the trigger electrode 6 is connected to the trigger circuit inside the flash lamp 1. 4.411
1vc discharge occurs.

となる。Reference numeral 12 denotes a charging/discharging capacitor, which is photoelectrically charged by a current power source 13 via a charging control switch 14, a transformer 15, a charging control reactor 16, and a rectifying diode bridge 17. Due to this charging, the charging/discharging capacitor 12
The charges accumulated in the flash lamp 1 are discharged from the flash lamp 1 via the discharge control IJ actor 18 when a trigger pulse voltage is applied to the trigger electrode 6.
．． It will discharge for 4 hours and a flash of light will be emitted from the flash lamp l. The energy of this flash fuses the undefined layer toner image on the recording paper P (FIG. 3) and fixes it on the recording paper P, or the flash energy is stored in the capacitor 12 and supplied by electrical energy Q. As is well known, Q is determined by the formula Q-4CV2. 1, C is the capacitance of the capacitor 12, and ■ is the photoelectric voltage. Therefore, in order to obtain sufficient flash energy, it is necessary to set the charging voltage (2) to a high level, and the charging voltage (V) is usually a high voltage of several hundred to several thousand volts.
