摘要:
A fixing member having a base layer and a surface layer, wherein the surface layer includes a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer, and having at least one pore communicating with an opening on an outer surface thereof. A composition containing perfluoropolyether and a fluoropolymer is contained in at least a part of the at least one pore. The fluoropolymer has a particular repeating unit composed of perfluoropolyether, and at least one structure selected from the group consisting of a T unit of siloxane and a Q unit of siloxane.
