Abstract
A photosensitive layer of an electrophotographic photoconductor has at least one phthalocyanine compound, wherein the photosensitive layer contains a metal phthalocyanine compound bonded by an o-phthalonitrile compound as a ligand. The o-phthalonitrile ligand is present in an amount from about 100 nmol to about 200 nmol with respect to 1 mol of the phthalocyanine. The resulting electrophotographic photoconductor exhibits a high potential retention rate. A method for making such an electrophotographic photoconductor is also disclosed wherein a photosensitive layer is formed by coating, with a coating layer, to obtain a photosensitive layer having a high potential retention rate.
