Abstract

An electrophotographic member comprising: a base material; an elastic layer on the base material; and a surface layer on the elastic layer, wherein the elastic layer comprises silicone rubber, the surface layer comprises fluoro rubber, a thickness of the surface layer is 3 µm or more, an elastic deformation power ηIT calculated from a load displacement curve, obtained with a nanoindentation test according to ISO 14577 by bringing a Vickers indenter into contact with an outer surface of the surface layer and setting a test load at 120 µN, is 30 to 50%, and a Martens hardness determined by the nanoindentation test at the outer surface of the surface layer is 12.0 to 18.0 N/mm<2>.
