ABSTRACT:
An electrophotographic process comprises the steps of:
developing an electric latent image with toner particle, the toner particle comprising 20-70 parts by weight of at least one resin selected from resins of Group A and 80-30 parts by weight of at least resin selected from resins of Group B, transferring the developed toner image to a paper having a smoothness of 5-130 seconds (measured by Bekk method), applying pressure to the transferred toner image to fix the toner image on said paper, and repeating at least said steps, in which said resins of Group A includes a low molecular weight polyethylene, a low molecular weight polypropylene, ethylene-ethyl acrylate copolymer, ionomer resin and ethylenevinyl acetate copolymer, and said resins of Group B includes natural resin modified maleic acid resin, natural resin modified pentaerythritol resin and natural resin modified glycerine resin.
