PROBLEM TO BE SOLVED: To provide a developing member in which nonuniform application is lessened even though an acrylic resin whose kind is different from the kinds of conventional ones is used as an acrylic resin applied together with a urethane resin. SOLUTION: The developing member for an electrophotographic apparatus includes: a rubber base material; and a surface layer which is disposed on the surface of the rubber base material and negatively charges toner by friction, the surface layer being composed of a mixture of urethane resin and acrylic resin. The surface layer is formed by applying a solution prepared by dissolving the mixture in a solvent. As the acrylic resin, a graft compound in which an aminoethyl group is grafted onto the principal chain composed of a methacrylic acid-methyl methacrylate copolymer is used.
