ABSTRACT:
A method and apparatus of electrophotography used for a printer or a copying machine, wherein a toner having no photoconductivity is applied on a surface of a photoconductive layer of a photoreceptor consisting of a transparent conductive layer and the photoconductive layer which are sequentially formed on a transparent substrate. The photoconductive layer is exposed from a side of the transparent substrate. Toner particles on an exposed region of the photoconductive layer are transferred to toner-receiving paper opposite the photoconductive layer so as to form a toner image. A process for developing a latent image can be omitted. In addition, a special toner such as a photoconductive toner having low sensitivity is not used, thereby forming a high-quality image.
