Fixing member, method for manufacturing the same, fixing apparatus, and image forming apparatus |
摘要 |
The present invention relates to a fixing member including a surface layer containing PFA, the fixing member being excellent in wear resistance and having high release properties to a toner. The fixing member includes a base member, an elastic layer provided on the surface of the base member, and a surface layer, wherein the surface layer contains a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer having a particular partial structure, and has a surface having a contact angle of 67 degrees or more as measured in a mixed liquid for a wetting tension test having a wetting tension of 31.0 mN/m. |
