ABSTRACT:
Disclosed is an organic laminated photosensitive material of the positive charging type comprising an electroconductive substrate, a charge-transporting layer formed on the substrate and a charge-generating and transporting layer formed on the charge-transporting layer. The charge-transporting layer is composed of a binder resin containing a hole-transporting substance, and the charge-generating and transporting layer is composed of a binder resin containing a charge-generating substance and a hole-transporting substance. In this laminated photosensitive material, an excellent sensitiveity is maintained even if the topmost charge-generating layer has a large thickness, and therefore, a high surface saturation charge voltage and an excellent printing resistance can be maintained in addition to an increased sensitivity.
