    摘要： Disclosed are a novel organic photoconductive material suitable as a charge-transporting material in a photosensitive layer of an electrophotographic photoreceptor or usable in various display devices, and an electrophotographic photoreceptor which uses the above organic photoconductive material in a photosensitive layer and which exhibits a high charge potential and high sensitivity and also exhibits little or almost no change in various properties in repeated use and can exhibit stabilized performances. The present invention provides an organic photoconductive material comprising a compound having a specific structure and an electrophotographic photoreceptor having a photosensitive layer containing the above photoconductive material.
