Zusammenfassung:A fixing member having an endless belt shape or a roller shape includes a base layer and a surface layer. The surface layer contains a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer, and has a pore communicating with an opening of an outer surface thereof. Perfluoropolyether is contained in at least a part of the pores. A ratio (E″(1)/E″(2)) is 0.60 to 1.00, where E″(1) is an average value of loss elastic moduli E″ of the surface layer in a direction orthogonal to a circumferential direction of the fixing member measured at a frequency of 10 Hz at 100 to 150° C., and E″(2) is an average value of loss elastic moduli E″ of the surface layer in a direction orthogonal to the circumferential direction of the fixing member measured at a frequency of 10 Hz at 100 to 150° C. after removal of the perfluoropolyether contained in the pore.
