Patent ID: 11669027

Abstract:
An electrophotographic belt including at least a base layer and a surface layer on or above the base layer, the surface layer including a binder resin and perfluoropolyether (PFPE), having a thickness of 2 μm or more. PFPE is removed to obtain a PFPE-removed surface layer, the PFPE-removed surface layer has pores having openings at an outer surface thereof. When assuming that the PFPE-removed surface layer is a solid-surface layer, a ratio of a total volume of the pores contained in the PFPE-removed surface layer to a volume of the solid-surface layer is 8 to 25%. A ratio of a sum of areas of the openings to a unit area (1 μm2) of the outer surface of the PFPE-removed surface layer is 10 to 35%, and the number of the openings per unit area (1 μm2) of the outer surface of the PFPE-removed surface layer is 10 to 500.
