    摘要: The improved dielectric member for carrying electrostatic latent image comprises a support and an overlying dielectric layer, with a thickness of from 3 to 70 .mu.m, that is formed of an polysiloxane/amic acid copolymer. The dielectric member has a relative dielectric constant of 2.0 to 6.0, a surface hardness of 300 to 1,500 on the Vickers scale, and exhibits high reliability in operating characteristics. It can be produced by a process in which the dielectric layer is formed on the support by applying an inorganic polymer compound film-forming material onto the support, and heating the coated layer in vacuum to cure.

    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.
