MONOLAYER ELECTROPHOTOGRAPHIC PHOTORECEPTOR

摘要

PROBLEM TO BE SOLVED: To provide a monolayer organic photoreceptor excellent in ozone resistance and free of defects such as image fog and a black band due to the lowering of electrification ability and the deterioration of sensitivity even when used in an image forming device having 5.0 ppm maximum concentration of ozone. SOLUTION: The monolayer electrophotographic photoreceptor has a photosensitive layer comprising a binder resin containing at least an electric charge generating agent and an electric charge transferring agent on an electrically conductive substrate and the oxygen permeability coefficient of the binder resin is <=35 cc mm/m2 day atm. Since the photoreceptor has very good ozone resistance, it is free of defects such as image fog and a black band even when used in an image forming device having a high concentration of ozone.
