Abstract:
A fixing member is provided which is excellent in durability and hardly undergoes the peeling of the surface layer even when used in a heating apparatus over a long term. The fixing member is an electrophotographic fixing member including a substrate, an elastic layer, an intermediate layer and a fluororesin-containing surface layer. The elastic layer includes a silicone rubber and sodium ions, and the intermediate layer includes an amino group-containing polysiloxane. The surface layer is formed by forming, on the intermediate layer, a primer layer including a copolymer, to which a phosphate group is bound, of tetrafluoroethylene and perfluoro(alkyl vinyl ether), forming, on the primer layer, a coating film including the copolymer of tetrafluoroethylene and perfluoro(alkyl vinyl ether) or a coating film including a copolymer of tetrafluoroethylene and hexafluoropropylene, and melting the copolymer in the primer layer and the copolymer in the coating layer.
