摘要： The invention relates to an electrophotosensitive material comprising an organic photosensitive layer and an inorganic surface protective layer, wherein at least an outermost part of the organic photosensitive layer contains a diphenylamine compound represented by a formula (1): wherein ‘A’ denotes a groups combined with two phenyl groups in the formula in a manner to jointly form a &pgr;-electron conjugated system. The electrophotosensitive material features more excellent durability because the compound functions as a binder for combining the organic photosensitive layer with the inorganic surface protective layer so that the surface protective layer is less prone to suffer cracks or delamination.

摘要： The present invention relates to an electrophotographic photosensitive member rotatably supported in an image forming apparatus. The electrophotographic photosensitive member includes a substantially cylindrical body and a photosensitive layer formed thereon and having a latent image forming area. The photosensitive layer is, when incorporated in the image forming apparatus, pressed harder at a middle portion than at end portions in axial direction of the latent image forming area, and a thickness at the middle portion is larger than at the end portions. The photosensitive layer may have a dynamic indentation hardness larger at the middle portion than at the end portions.

摘要： The present invention relates to an electrophotographic photosensitive member and an image forming apparatus provided with the same. The electrophotographic photosensitive member includes a substantially cylindrical body and a photosensitive layer having a latent image forming area formed on the body. The photosensitive layer includes a first end in the axial direction of the latent image forming area and a second end located opposite to the first end in the axial direction. The first end is pressed harder than the second end. In the photosensitive layer, thickness or dynamic indentation hardness at the first end at one side of the latent image forming area is larger than thickness or dynamic indentation hardness at the second end located opposite to the first end in the axial direction of the latent image forming area.
