ABSTRACT:
The present invention presents a rotatory member for fixing toner image onto a support member supporting toner image, which is constituted of a core member, an elastic layer provided on the core member, an intermediate layer provided on the elastic member, and a surface layer provided on the intermediate layer. The whole elastic layer is covered with the above intermediate layer, and also the coverage with the above intermediate layer is extended to the portion which blocks movement of the mold release agent provided around the journal portion of the core member. With such constitution, contamination within the main device with the mold release agent reaching from the rotatory member to the main device can be prevented.
