Electrophotographic photoreceptor containing polycarbonate resin as a binder and method for preparation thereof

摘要

A novel electrophotographic photoreceptor and a method of preparation therof 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 (* CHEMICAL STRUCTURE *) (I) 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.
