ABSTRACT:
An electrophotographic photoreceptor, including an electroconductive substrate; and a photosensitive layer overlying the electroconductive substrate, which includes a crosslinked layer at the surface thereof, wherein the crosslinked layer is formed by a method including:coating a coating liquid, which includes a solvent; a radical polymerizing monomer having three or more functional groups and no charge transportable structure; and a radical polymerizing compound having a charge transportable structure on the photosensitive layer; andirradiating the coating liquid to be hardened while the surface of the photosensitive layer is controlled to have a temperature not higher than a boiling point of the solvent.
