Abstract
A high quality electrophotographic member that is excellent in deformation recovery property under high-temperature and high-humidity and that also satisfies filming resistance under low-temperature and low-humidity is provided.
The electrophotographic member includes a substrate, an elastic layer, and a surface layer containing a urethane resin, wherein the urethane resin has a partial structure having at least one structure selected from the group consisting of structures of structural formulae (1) to (7) between adjacent two urethane linkages, and the urethane resin further has a partial structure derived from a reaction of a compound represented by a structural formula (8) with a polyisocyanate.
