    摘要： An electrophotographic photosensitive element, e.g. for a photocopier or laser printer, comprises a substrate (101) and a plurality of layers on the substrate including a photoconductive layer (103) of a-­Si:H and a protective and lubricating layer (107) which is outermost from said substrate. To provide wear resistance and long life-time of the protective and lubricating layer, this layer comprises a microporous solid material (105) having a pore structure which extends substantially over the whole thickness of the material and a hydrophobic lubricant (106) carried by said solid material. The lubricant is at least one of a liquid film and a non-particulate solid film, and provides at least part of the outer surface of the element and is present also in the pores of said microporous solid material.

    摘要： An electrophotographic photoreceptor comprising a photoconductive layer (103) comprising a photoconductor, a support (101, 102) for the photoconductive layer (103) and a surface layer (107) formed on the photoconductive layer (103) and comprising a curable resin film (105) and inorganic insulator pieces (106) having a size larger than the film thickness of the curable resin film (105). In order to prevent the image blurring of an a-Si:H photoreceptor, on the outermost surface of the photoreceptor was formed a surface layer having a structure in which inorganic insulator pieces (106) have protruded from the curable resin film (105). Since the curable resin (105) is of high resistance and shows no quality change by corona irradiation, and besides the protruding inorganic insulator pieces (106) prevent the abrasion of the resin, the surface layer (107) having a long life and excellent humidity resistance, durability for corona irradiation and abrasion resistance can be realized. Further, by covering the surface layer (107) with a fluorine-containing lubricant, the surface layer (107) having a low friction coefficient and excellent cleaning characteristics is obtained, and besides the resin constituting the surface layer (107) absorbs little moisture. As a result, it becomes possible to use the a-Si:H photoreceptors without a heater. Also, the surface layer (107) of the present invention can be removed and then re-formed.
