Abstract
The present invention is directed to providing a fixing member that can form high quality electrophotographic images. The fixing member includes a substrate, an elastic layer on the substrate and a surface layer bonded to the elastic layer with an adhesive layer. The surface layer contains a fluorine resin. The surface layer having a thermal resistance in the thickness direction of 3.0×10m·K/W or more and 1.3×10m·K/W or less and the peel adhesion strength between the surface layer and the elastic layer is 3.0 N/cm or more and 20.0 N/cm or less, while the elastic layer undergoes a cohesive failure in a peel test between the surface layer and the elastic layer and the fluorine resin contains a tetrafluoroethylene/perfluoroethyl vinyl ether copolymer, the polymerization ratio of perfluoroethyl vinyl ether in the copolymer being 3.0 mol % or more and 5.8 mol % or less.
