Abstract (en)

[origin: EP0642064A2] A heat-fixing apparatus for use in an electrophotographic apparatus such as a copying machine. It comprises a substrate roller formed of a material having a heat conductivity of 0.7 kcal/mhk or less, a resistant heat-generating layer provided on the surface of the roller, and a surface coat layer provided on the resistance heat-generating layer. This heat-fixing apparatus has a very high heat efficiency, and can perform heat-fixing of a toner at a low consumption of electric power. In addition, since the heating is carried out rapidly, the rising time is markedly shortened, and it is not necessary to perform pre-heating. In this respect, too, the electric power to be consumed is decreased. Furthermore, since it is a roller-type fixing method, it can effectively cope with high-speed copying. Moreover, because the apparatus has a large strength, the apparatus can be effectively made light in weight. <IMAGE>
