摘要:
A process for fixing a toner image formed on a support by means of a heat roller according to the present invention comprises fixing the toner image developed by using a toner containing as the binder resin a styrene-butadiene copolymer containing 70 to 95 mole % of styrene.
摘要:
An electrophotographic method comprises developing an electric latent image formed on a photosensitive member comprising a photoconductive material and containing a first color forming agent in a surface for forming a visible image with a charged toner particle containing a second color forming agent, and heating to cause a thermal color forming reaction therebetween resulting in formation of a colored fixed image on the photosensitive member and a receiving sheet comprising a color forming agent (B) and a material having a melting point from 40.degree. to 130.degree. C.
