Abstract
A negative-electrification type electrophotographic photoreceptor which has an undercoat layer slightly soluble or insoluble in solvents and retains stable properties, and to provide a contact electrification type electrophotographic apparatus employing the photoreceptor and less apt to suffer dielectric breakdown. The electrophotographic photoreceptor comprises an electrically conductive support having thereon an undercoat layer and a photosensitive layer, in which the undercoat layer comprises an electron-transporting pigment and a reactive organometallic compound. This electrophotographic photoreceptor is suitable for use in an electrophotographic apparatus in which the photoreceptor is charged by applying a voltage to a charging member disposed so as to be in contact with the photoreceptor, in particular, an erase-less electrophotographic apparatus.
