Abstract
An electrophotographic member includes an electroconductive substrate bearing a monolayer surface layer formed thereon. The surface layer has a matrix containing a crosslinked resin binder, and holds at least one particle containing an inorganic layered compound that has an ion exchange capacity. At least a portion of the particle is exposed from an outer surface of the surface layer. The matrix has an elastic modulus of at least 200 MPa, measured in a thickness direction of the surface layer from the outer surface to a depth of 0.1 μm.
