Abstract

An electrophotographic member (1) including an electro-conductive substrate (2), an elastic layer (3), and a surface layer (4), the surface layer containing a fine particle and a binder resin, and having a thickness of less than 1.0 µm, the fine particles having an average particle diameter of from 0.1 µm to 0.9 µm, the fine particles having a volume occupancy of 60 vol% to 99 vol% with respect to 100 vol% of the binder resin in the surface layer, the elastic modulus E1 of the fine particle being 1,000 MPa or more, and the elastic modulus E2 of the binder resin being 2 MPa to 200 MPa, and MD-1 hardness H1 of the surface layer being 50° to 100°, and a difference (H1-H2) between the H1 and MD-1 hardness H2 of the elastic layer being 5° or more.
