Abstract
An electrophotographic photoconductor has a conductive substrate and a photosensitive layer. The photosensitive layer is laminated on the conductive substrate and includes at least phthalocyanine compound as a photoconductive material. In the photosensitive layer, the content of o-phthalonitrile polymer except the phthalocyanine compound is in a range of 100 nmol to 200 mmol with respect to 1 mol of the phthalocyanine compound. Thus, the electrophotographic photoconductor has an excellent surface-charge retention.
