Fixing member and manufacturing method therefor, fixing device, and image forming apparatus

摘要

The present invention relates to a fixing member having high abrasion resistance and being excellent in toner releasability, and a method of manufacturing the fixing member. The fixing member according to the present invention includes: a base member; an elastic layer formed on a surface of the base member; and a surface layer, in which the surface layer contains a tetrafluoroethylene-hexafluoropropylene copolymer having a specific partial structure and has a surface that forms a contact angle of 65° or more with respect to a wetting tension test mixture having a wetting tension of 31.0 mN/m.
