| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide excellent wear resistance, enhance the uniformity of potential by endurance, make toner fusion difficult to occur, and supply a satisfactory image by constituting the surface layer of an electrophotographic photoreceptor so that the universal hardness value (Hu) is a specified value in a surface film hardness test under a specified environment, and the plastic deformation rate of the surface layer by an indenter satisfies a specified condition. SOLUTION: The surface of an electrophotographic photoreceptor having a conductive support and an organic photosensitive layer is set so that Hu is 230 N/mm2 |
