ELECTROPHOTOGRAPHIC PHOTORECEPTOR AND ELECTROPHOTOGRAPHIC APPARATUS

摘要

An electrophotographic photoreceptor that without detriment to excellent electrophotographic performance, realizes coating of any defects on a conductive substrate and excels in repetition stability and environmental performance. There is provided an electrophotographic photoreceptor having a photoreceptive layer superimposed via an undercoat layer on a conductive support, characterized in that the undercoat layer contains a polyimide resin and that at least one of the compounds of the following formulae is contained as a charge transfer agent of the photoreceptive layer.
