Abstract
A photoconductor for electrophotography containing an undercoating film, that remains largely unaffected by environmental factors. The photoconductor exhibits stable electrical properties and allows for thickening of the undercoating film so that dielectric breakdown is not caused even when a contact charging method is used. The photoconductor includes a conductive substrate, an undercoating film on the conductive substrate and a photosensitive film on the undercoating film. The undercoating film contains a conductive polymer, an alkaline metal salt, a binder resin and an inorganic pigment.
