Abstract
A positive charge type organic photoconductor in which the surface of the photoconductor having a film thickness of from 10 to 30 .mu.m and containing at least from 15 to 40% by weight of a phthalocyanine type photoconductive compound in a resin binder, is treated with a reactive monomer or oligomer capable of extinguishing ionic active and radical active parts.
Claims7
A positive charge type organic photoconductive layer comprising:
- a film containing 15% to 40% by weight of a .chi. type crystal of a metal-free phthalocyanine compound in a binder resin, said film having a thickness of from 10 .mu.m to 30 .mu.m;
- and
- a coating on said film, said coating being a reactive product of a mixture of a diglycidyl ether epoxy resin of bisphenol F and an amine compound.
A positive charge type organic photoconductive layer, comprising:
- a film comprising a .chi. type crystal of a metal-free phthalocyanine compound in a binder resin;
- and
- a coating on the film, the coating being a reactive product of a mixture of a diglycidyl ether epoxy resin of bisphenol F and an amine compound.
