    摘要： An electrophotographic photoreceptor is disclosed, comprising an electrically conductive substrate having provided thereon at least a photoconductive layer and a surface layer, wherein the photoconductive layer comprises (a) a charge transporting layer mainly composed of amorphous silicon containing at least one of hydrogen and a halogen and at least one selected from carbon, oxygen, and nitrogen and (b) a charge generating layer composed of amorphous silicon containing at least one of hydrogen and a halogen or amorphous silicon containing at least one of hydrogen and a halogen and at least one selected from germanium and tin, and the surface layer is composed of at least one of an organic polymer material and an inorganic polymer material having dispersed therein an electrically conductive fine powder. The photoreceptor shows less dark decay of the charged potential, does not cause image blurring under a high-humidity condition, and forms an image having no moire in a laser printer using a coherent light source.

    摘要： An electrophotographic photoreceptor comprising a conductive substrate, a photoconductive layer formed on the substrate, and a surface layer formed on the photoconductive layer, wherein the surface layer comprises a polymer mainly composed of a siloxane bond and an imide bond. The photoreceptor has small dark decay and excellent mechanical strength and causes no image blurring under high humidity conditions and therefore can be used in a general electrophotographic process. When used in a laser printer using a coherent light source, the photoreceptor produces high quality images free from a Moire fringe.

    摘要： An electrophotographic photoreceptor comprising a conductive substrate having provided thereon a photoconductive layer is disclosed, said photoconductive layer containing a high polymeric compound comprising a repeating unit comprised of a tetracarboxylic acid anhydride skeleton and a divalent organic group skeleton having an aromatic nucleus, said two skeletons being bonded via a nitrogen atom. Said high polymeric compound is formed by co-deposition of a tetracarboxylic acid anhydride compound and an aromatic diamine compound. The photoreceptor exhibits high sensitivity, high durability, and excellent image quality retention even when used repeatedly or in a high humidity environment.
