PURPOSE:To obtain a photosensitive body having high sensitivity providing plural peaks in absorption spectrum by laminating >=two kinds of charge generating layer and dissolving each laminated charge generating layer in each other at its interface. CONSTITUTION:In the title electrophotographic sensitive body, >=two kinds of charge generating layer are laminated and each laminated charge generating layer dissolves another charge generating layer in each other at its interface. If an interface is present between two laminated charge generating layers, an injection efficiency of a charge carrier formed in a lower layer is inhibited remarkably because the charge carrier is trapped at an interface when the carrier is injected into an upper layer, thus, the number of the carrier reaching a charge transfer layer decreases. By this constitution, interfacial barrier is eliminated, and a photosensitive body having high sensitivity and plural peaks in an absorption spectrum is obtd. The sensitive body causes less fluctuation of potential when used repeatedly. |
