Abstract
An electrophotographic photoreceptor comprising a cylindrical electrically conductive substrate having thereon at least a photoconductive layer, the conductive substrate having a marking portion in which the light reflectance of the surface of the conductor substrate has been changed by a laser light treatment, a method for producing the photoreceptor, and an image correcting method using the photoreceptor.
Claims14
An electrophotographic photoreceptor comprising a cylindrical electrically conductive substrate having thereon at least a photoconductive layer, said conductive substrate having a marking portion in which the light reflectance of the surface of said conductor substrate has been changed by a laser light treatment, wherein the light reflectance of said marking portion is not higher than 50% of the light reflectance of said conductive substrate at the portion other than said marking portion, in terms of a relative light reflectance.
A method of producing an electrophotographic photoreceptor comprising a cylindrical electrically conductive substrate having thereon at least a photoconductive layer, said method comprising the steps of:
- forming on said conductor substrate a marking portion in which the light reflectance of the surface of said conductor substrate is changed by a laser light treatment, wherein the light reflectance of said marking portion is not higher than 50% of the light reflectance of said conductive substrate at the portion other than said marking portion, in terms of a relative light reflectance;
- and
- forming a photoconductive layer on said conductive substrate including said marking portion.
