Disclosed is an electrophotographic photoreceptor in which an organic lubricant is provided on the surface of an organic photoconductive layer or on a protective layer formed on the organic photoconductive layer. Elements of the organic lubricant are partly exposed from the surface of the organic photoconductive layer or the protective layer while the remainder portions of the elements are embedded or fixed by chemical reaction in the surface region of the photoconductive layer or the protective layer so that the exposed portions of the elements of the organic lubricant provides a lubricating surface layer. The lubricating surface layer supresses wear of the photoreceptor thereby enabling the photosensitive layer to withstand a long repeated use without impairing electrophotographic characteristics.
