摘要:
A fluorine rubber composition used for the surface layer material of a fixing member to fix a toner transferred onto a recording material comprises fluorine rubber having a polymerization degree based on vinylidene fluoride. The fixing member includes a base material, and a surface layer material disposed on the surface of the base material, and the surface layer material contains fluorine rubber having a polymerization degree base on vinylidene fluoride. Preferably, the fluorine rubber composition contains a reinforcing agent, antacid, vulcanizing agent, vulcanization accelerator, spherical filler, and solvent. Preferably, the fixing member has numerous fine convex portions on its surface. Accordingly, the amount of the toner adhering to the surface of the fixing member is reduced. Thus, generation of offset trouble can be reliably prevented for a long period of time. As a result, the durability of the fixing member will be improved.
