ABSTRACT:
A negatively-chargeable electrophotographic photosensitive member, has, between a cylindrical substrate and a photoconductive layer, a first lower-part layer formed of a non-single crystal material containing silicon atoms and a second lower-part layer formed of a non-single crystal material containing silicon atoms, and on its photoconductive layer has an upper-part layer formed of a non-single crystal material containing silicon atoms. The first lower-part layer is a layer containing a periodic-table Group 13 element, and the upper-part layer has a region capable of retaining electrification charges.
