Abstract
This invention presents an electrophotographic photosensitive material wherein a charge transporting layer and a charge generating layer are laminated in this order on a conductive substrate, and the charge generating layer contains N-type dye and P-type dye at a ratio of 40/60 to 90/10 (N-type dye/P-type dye) by weight. This electrophotographic photosensitive material is especially superior in reproductivity of red-colored originals as well as having a high sensitivity.
