<p>PURPOSE:To provide an image forming method by which a high-grade copied image having proper image density and no surface fog can stably be fed. CONSTITUTION:In this image forming method utilizing a system in which an untransferred toner on a latent image carrier after development and transfer is recovered by cleaning and reused, a toner contg. polyester resin as a bonding resin and having inorg. fine particles of 30 to <100nm average particle diameter stuck to the surface is used. The polyester resin is obtd. by bringing polyol components including diol represented by formula I and polycarboxylic acid components including dicarboxylic acid represented by formula II or III or its anhydride and trimellitic acid or its anhydride into condensation polymn. In the formula I, R<1> is 2-4C alkylene, each of (x) and (y) is an integer and the mean value of the sum of (x) and (y) is 2-16. In the formulae II, III, each of R<2> and R<3> is 4-20C hydrocarbon.</p> |
