Transparent electrophotographic photoreceptor comprising specific hydrazone and benzidine compounds as photoconductors

摘要

A transparent electrophotographic photoreceptor comprising a conductive support having provided thereon a photosensitive layer is disclosed, wherein said photosensitive layer contains a combination of at least one of specific hydrazone compounds and at least one of specific benzidine compounds as photoconductive substances. These photoconductive substances are prevented from crystallization and precipitation on the surface of the photoreceptor so that the photoreceptor exhibits satisfactory stability before and after image formation even when preserved for long periods of time or under a high temperature condition.
