    摘要： An electrophotographic photosensitive member is comprised of a support and a photosensitive layer formed on the support. The electrophotographic photosensitive member has a surface layer which contains a resin having at least one of the structural units represented by the following formula: ##STR1## wherein the bond represented by a broken line may be present, and when present, m is 4 and when m is 6, n represents an integer of 0 or more, and R.sub.1 and R.sub.2 represent each independently hydrogen, halogen, hydroxy, a substituted or unsubstituted alkyl, a substituted or unsubstituted unsaturated aliphatic hydrocarbon, a substituted or unsubstituted aryl, a substituted or unsubstituted cycloalkyl, a substituted or unsubstituted cyclodienyl, a substituted or unsubstituted alkoxy, a substituted or unsubstituted carbonyl, or a substituted or unsubstituted heterocyclic group.

    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).

    摘要： An electrophotographic photosensitive member is constituted by disposing a protective layer and a photosensitive layer on an electroconductive support in this order. The protective layer is characterized by containing an electroconductive particles, fluorine-containing resin particles and a binder resin. The photosensitive layer is suitable for providing an electrophotographic apparatus showing excellent electrophotographic characteristics such as a high photosensitivity and a low residual potential and also providing good image forming properties under any environmental condition, improved pause memory characteristics and a decreased transfer memory.
