摘要:
A selenium photoconductor has a charge transport layer and a charge generation layer formed on a conductive substrate. Both the charge generation layer and the charge transport layer are made from a selenium-arsenic alloy, with the charge generation layer having a concentration of arsenic greater than the concentration of arsenic in the charge transport layer. This concentration distribution results in a photoconductor having excellent charge-generation efficiency and mobility. In an alternate embodiment, a halogen is doped into the charge generation layer and charge transport layer. The resulting photoconductor is useful in large-scale, high speed printing operations.
摘要:
A xerographic photoreceptor primarily formed by amorphous silicon material is disclosed, wherein the xerographic photoreccptor is a photosensitive drum used in copying and manufactured by the plasma enhanced low pressure chemical vapor deposition system. Such a drum has a higher resolution, and a longer lifetime. In this structure, an Al2O3 oxidization layer is grown on an aluminum substrate. Then a n type hydrogenated amorphous silicon blocking layer is grown on the aluminum substrate with Al2O3 oxidization layer. Then an intrinsic hydrogenated amorphous silicon charge generating transmission layer is grown on the n type hydrogenated amorphous silicon blocking layer. Finally a hydrogenated amorphous carbon surface protecting layer is grown on the intrinsic hydrogenated amorphous silicon charge generation transport layer for forming a xerographic photoreceptor with a multiple layer structure. Not only the manufacturing process is simple, but also a lager area is achieved in preparing a film manufacture and thus, the cost will be reduced.

摘要:
A process for manufacturing an electrophotographic photosensitive member is disclosed in which a source gas is decomposed by the use of a high-frequency power in a rector to deposit sequentially on a conductive substrate i) a photoconductive layer comprised of an amorphous material composed chiefly of silicon atoms and ii) a surface layer comprised of an amorphous material composed chiefly of carbon atoms and containing hydrogen atoms. The process has the steps of forming the photoconductive layer in a first reactor, and forming the surface layer in a second reactor. This process can produce an electrophotographic photosensitive member having an a-Si photoconductive layer and a-C:H surface layer or a-C:H(Si) surface layer in a good efficiency and at a low cost. Also disclosed is an electrophotographic photosensitive member manufacturing apparatus which carries out the process.
