ABSTRACT:
A recording apparatus for forming a toner image with simultaneous application of a light image and toner is provided. An endless imaging belt includes a transparent substrate, an inner conductive layer formed on the substrate, a photoconductive layer formed on the inner conductive layer, an outer conductive layer formed on the photoconductive layer, and a surface layer formed on the outer conductive layer. With a positive bias applied to the outer conductive layer and a negative bias to the inner conductive layer, a light image is applied to the imaging member from the transparent substrate side and at the same time a film of positively charged toner is applied to the opposite side of the imaging member, so that a toner image is directly formed on the imaging member by selective deposition of toner according to a light pattern of the light image.
