Electrophotographic photoreceptor

摘要

An electrophotographic photoreceptor which is highly sensitive to light having a wavelength in the oscillatory wavelength region of semiconductor laser and responds quickly and is excellent in other electrophotographic characteristics and which consists an electroconductive support, a charge-generating layer and a charge-transfer layer, the two layers being placed on the support, and said charge-transfer layer containing a specific butadiene compound having formula (I); <IMAGE> (I) and a monophenol type antioxidant, the weight ratio of the monophenol type antioxidant/the butadiene compound ranging from 5/95 to 40/80.
