ABSTRACT:
The present invention is concerned with a photosensitive material for electrophotography that comprises forming a photosensitive layer on a substrate, wherein said photosensitive layer is constructed by laminating a charge transfer layer, a first charge carrier generating layer and a second charge carrier generating layer in order from said substrate side to free surface, and said charge transfer layer and second charge carrier generating layer each has a band gap wider than that of said first charge carrier generating layer.
