ABSTRACT:
According to the present invention, an enamine compound having a specific structure is used as an organic photoconductive material. This enamine compound is obtained based on asymmetrical secondary naphtylamine which is readily available at a lowest price, by introducing phenyl groups containing substituents, as constituents units of the enamine part and presents excellent compatibility with binder resins, will not present detrimental effects such as partial crystallization at film forming and have a high charge mobility. The compound is able to realize highly reliable electrophotographic photoreceptor and an image forming apparatus which present a high electrostatic potential, high sensitivity and high enough light response and are excellent in durability and will not degrade in these characteristics under a low-temperature environment or in a high-speed process and will not lower in these characteristics even due to exposure to light.
