    摘要： An electrophotographic photosensitive member is provide which inhibits recovered toner from leaking out of the edge portion at the time of long-term use, and has good durability. Each of at least both edge portions of the surface layer of the electrophotographic photosensitive member has a region in which independent depressed portions are formed at a density of ten or more portions per 100 μm square. An average depth Rdv-A, an average short axis diameter Lpc-A, and an average long axis diameter Rpc-A, of the depressed portions are respectively in specific ranges. When an angle formed between the circumferential direction of the electrophotographic photosensitive member and the long axis of each of the depressed portions is represented by θ, the depressed portions are formed so that the angle θ satisfies the relationship of 90°

    摘要： An object of the present invention is to improve a phenomenon of the life-shortening of the endurance life due to scratch occurring when recesses of a fixed dimple shape are formed on the surface of the surface layer, in order to inhibit the chattering and folding back of a cleaning blade and the fracture of an edge, which occurs because friction between the surface layer of the surface of an electrophotographic photosensitive member and an abutting member is high; and particularly to improve the above described problems, from initial printing through printing on many sheets, which become particularly remarkable when using an electrophotographic photosensitive member with the use of a curable resin that is improved so as to have a high elastic deformation rate for the surface layer, in order to improve the strength of the surface layer, for the purpose of increasing the durability of an electrophotographic photosensitive member. An electrophotographic photosensitive member for achieving the object, which has a support and an organic photosensitive layer, is characterized in that the electrophotographic photosensitive member has dimple-shaped concavities formed on the surface of the surface layer of the electrophotographic photosensitive member, and further has the recesses with the same pattern as that on the surface of the surface layer, formed on the interface created between the surface layer of the organic photosensitive member and the layer directly under the surface layer (a subsurface layer).
