PURPOSE:To fix in high speed at comparatively low temp. without causing the generation of an offset development etc. by fixing a toner image to a sheet to be fixed by a heating roller by using toner contg. a coloring material, a styrene resin and a low moleculer weight propylene polymer. CONSTITUTION:Toner contg. a copolymer of styrene contg. >=25% styrene to the total weight of a styrene resin and other monomer or a styrene homopolymer, a polypropylene polymer having low molecular weight (<=10,000 weight average molecular weight) and a coloring material such as carbon black, is used. A plasticizer and a dispersion improver etc. may be contained if necessary. This toner is fixed to a sheet (a copying paper etc.) to be fixed at comparatively low temp. without causing the generation of an offset development to a carrier, a photoreceptor and a roller etc., and in high speed. |
