    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-like recesses 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).

    摘要： The present invention relates to a stilbeneamine derivative represented by a formula (1):
    wherein Ar 1 and Ar 2 each denote an aryl group; Ar 3 denotes an arylene group; Ar 4 denotes an arylene group or divalent heterocyclic group; provided that when a thiophene ring in the formula is 2-thiophenyl, 'n' is 1 and when the thiophene ring is 3-thiophenyl, 'n' is 0 or 1, and also relates to an electrophotosensitive material comprising a photosensitive layer containing this derivative. The derivative is excellent in electric charge transferring capability, compatibility with a binder resin and stability, thus offering the electrophotosensitive material superior to the prior-art products in sensitivity and repeatability.
