ORGANIC PHOTOCONDUCTIVE MATERIAL AND, USING THE SAME, ELECTROPHOTOGRAPHIC PHOTORECEPTOR AND IMAGE FORMING DEVICE

摘要

An organic photoconductive material comprising an enamine compound of specified structure. This enamine compound is from most inexpensive and readily available asymmetric secondary naphthylamine. Further, the enamine compound excels in the compatibility with a binder resin having a substituted phenyl group introduced therein as a structural unit of enamine moiety, being free from negative effects, such as partial crystallization, at the film formation and exhibits a high degree of charge transfer. The enamine compound realizes an image forming device or electrophotographic photoreceptor of high reliability which exhibits high charge potential, high sensitivity and satisfactory photoresponse and excels in durability, these properties not deteriorated even in use in low-temperature environment or high-speed process and also not deteriorated even by photoexposure.
