ABSTRACT:
An electrophotographic photoreceptor consists of an intermediate layer on a conductive substrate. A photosensitive bilayer is coated on the intermediate layer. The outermost layer if the photosensitive bilayer contains a combination of an ester phosphite antioxidant and a hindered phenol antioxidant. This organic photoreceptor has improved resistance to performance degradation and degradation in repetition characteristics from exposure to active gases (such as ozone). A method of producing the electrophotographic photoreceptor according to the invention is also taught.
