Abstract

PURPOSE: To provide a title toner with good heat depositing property and without generating offset or sticking to a heat depositing roll obtained by grinding a reaction product of toner stock material mixture based on a resin having carboxylic acid group and a metal oxide.
CONSTITUTION: A toner stock material mixture which is based on a resin having carboxylic acid group such as styrene-isobuthy methacrylate-methacrylic acid copolymer or the like and 0.1W60wt% of metal oxide such s ZnO, TiO2 or the like, and which, according to necessity, contains a charge controlling agent, a coloring agent, a flow property improver or the like is kneaded and reacted on a roll mill at 100W200°C for 5W60min to obtaine a reaction product having M.I. which is 1/3W1/30 of M.I. of the said resin and softening point of 50W200°C. This reaction product is cooled and ground to a particle size of 0.1W100μm to obtain an imaging toner for developing electric or magnetic latent image.
