Abstract
An electrophotographic member includes an electro-conductive substrate, and an elastic layer as a surface layer, the elastic layer constituted by a single-layer, wherein the elastic layer includes a first resin, a second resin and an anion, the first resin is a crosslinked urethane resin, and the crosslinked urethane resin is a resin having a specific cationic structure in the molecule, the second resin is at least one of a crosslinked acrylic resin having an ether bond and a crosslinked epoxy resin having an ether bond, and in a first area of the elastic layer, the first are being from an outer surface of the elastic layer to a depth of 0.1 μm, the first resin and the second resin form an interpenetrating polymer network structure.
