ABSTRACT:
There is provided an organic photoconductive material that can realize an electrophotographic photoreceptor which is not only excellent in charge transporting ability but also excellent in solubility in a solvent and compatibility with a resin and moreover, which is excellent in both electric properties and durability, and the organic photoconductive material that is useful also as a raw material compound for various types of functional materials. An asymmetric bis-hydroxyenamine compound represented by the following structural formula (1aa) is provided. The compound is allowed to be contained in a charge transporting layer or a surface protective layer of an electrophotographic photoreceptor. This leads realization of the electrophotographic photoreceptor which is excellent in electric properties and durability and can stably form an image of high quality being free of an image defect such as a black spot.
