摘要:
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.
摘要:
A novel electrophotographic photoreceptor and a method of preparation thereof are disclosed. The photoreceptor is characterized in that the photosensitive layer contain a specific carbonate resin binder resin having a weight average molecular weight on not less than 200,000. The resin is preferably a polycarbonate resin which contains repeating units represented by the formula
wherein R¹, R², R³, R⁴, R⁵ ,R⁶, R⁷ and R⁸ are respectively and independently a hydrogen atom, a lower alkyl group, a halogen atom or an unsubstituted or substituted aromatic group; and R⁹ and R¹⁰ are respectively and independently a hydrogen atom, a lower alkyl group, an unsubstituted or substituted aromatic group, or form a ring or a carbonyl group together with the linking carbon atom. The method is characterized in that the photosensitive layer contains a polyocarbonate having a weight average molecular weight of not less than 200,000 as a binder resin and is formed by spray coating or spiral coating.
