<P>PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor, which achieves reduction of an environmental load in the manufacturing process of the photoreceptor and improvement in production stability, which has little variation in sensitivity by dependence on an environment and high responsiveness even in a low temperature and low humidity environment, which is small in size with a fast image forming speed, and which has high reliability capable of giving high-quality images even in an environment such as low temperature and low humidity. <P>SOLUTION: The electrophotographic photoreceptor includes: an intermediate layer; and a lamination type photosensitive layer having a charge generating layer containing a charge generating substance and a charge transporting layer containing a charge transporting substance, layered in this order, or a reverse lamination type photosensitive layer, or a monolayer type photosensitive layer containing a charge generating substance and a charge transporting substance; the layers formed in this order on a conductive support body. The intermediate layer contains at least a block isocyanate compound and a binder resin having an active hydrogen-containing group reactive with an isocyanate group. In the photosensitive layer, the charge transporting substance contains a diphenylethenyl group-substituted triphenyl amine compound. <P>COPYRIGHT: (C)2012,JPO&INPIT |
