Abstract
Provided is an electrophotographic member including an electro-conductive substrate and a surface layer on the substrate. The surface layer contains a urethane resin and a first polymer having a specific nitrogen-containing structure. The urethane resin has a structure derived from a second polymer containing a fluorine atom or a structure derived from a third polymer containing a fluorine atom and a silicon atom. The surface layer contains nitrogen atoms derived from the nitrogen-containing structure at a specific ratio in a region from the outer surface of the surface layer to a depth of 300 nm, and the atomic ratios of nitrogen atoms, fluorine atoms, and silicon atoms in a region from a depth of 100 nm from the outer surface of the surface layer to a depth of 300 nm and a region from the outer surface to a depth of 10 nm have specific relationships.
