摘要:
An electrophotographic image forming member for forming color images including an organic photosensitive layer sandwiched between a dielectric layer and a conductive layer. The photoconductive layer includes a first charge generation layer adjacent to the conductive layer, a charge transfer layer on the first charge generation layer and a second charge generation layer on the charge transfer layer. During exposure, resistance of the photosensitive layer is reduced so that charges can flow through the photosensitive layer to create oppositely charged portions of the image forming member corresponding to a desired image of each color. Appropriately charged color toner adheres to the surface of the image forming member in the form of the desired image. After each color toner image is formed, the completed color image is transferred to a transfer medium.
