Abstract
A photovoltaic photo-receptor includes a glass substrate, a transparent electrode, a plurality of photovoltaic layers which are sequentially laminated and formed and mainly composed of a-Si having photovoltaic functions, and a surface layer formed on the uppermost photovoltaic layer and composed of a-SiN. When a light image is irradiated from an LED array head, photovoltaic voltges are generated on the respective photovoltaic layers in accordance with the light image, whereby an electrostatic latent image having a potential which is established by adding the voltages generated at the respective photovoltaic layers is formed on the surface layer. A toner to which a developing bias is applied is supplied from a magnetic brush to be brought into contact with the surface layer of the photovoltaic photoreceptor, so that the electrostatic latent image is toner-developed. A toner image is transcribed onto a paper by a transcribing roller which is applied with a transferring bias.
