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

摘要： An electrophotographic photosensitive element, e.g. for a photocopier or laser printer, comprises a substrate and a plurality of layers on the substrate including a photoconductive layer of a-Si:H and a protective and lubricating layer 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 having a pore structure which extends substantially over the whole thickness of the material and a hydrophobic lubricant carried by said solid material. The lubricant includes a liquid film and often times 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： The present invention is aimed at providing a magnetic disk and a magnetic disk apparatus both of which have a high performance lubricating film which makes continuous sliding endurance and low adhesiveness compatible, and a lubricating film having a self repairing function which makes it possible to recombine scratched off lubricating agent from the magnetic disk surface by sliding with a head onto the magnetic disk surface. The lubricating film comprises at least two kinds of lubricating agents each of which forms an individual layer, the layers being laminated. An adhesion enhancing layer is formed between a magnetic film and a lubricating agent at the surface of the magnetic disk, and the adhesion enhancing layer is fixed onto the magnetic film surface. Then, the adhesion enhancing layer and the lubricating agent are combined. The adhesion enhancing layer and the lubricating agent form a salt or complex body, and the lubricating agent can repeat adsorption and desorption with the adhesion enhancing layer reversely by a thermal reaction.
