ABSTRACT:
An image-forming apparatus which does not unfavorably influence its surrounding environment when in use and is excellent in durability of use and safety is provided. In the image-forming apparatus, a photosensitive layer is disposed on the outer surface of a closed-loop substrate drum, while a charge device, an exposure device, a developing device, a transfer device, a fixing device, and a cleaning device are provided around the substrate drum. The substrate drum is made of a light element. The charge device is constituted by a charging X-ray generation member, which is disposed within the substrate drum and emits an X-ray through the substrate drum and photosensitive layer so as to electrolytically dissociate the air on the surface of the photosensitive layer, and an electric-field application member which guides, by means of an electric field, a gaseous ion formed by this electrolytic dissociation to the surface of the photosensitive layer. The cleaning device is constituted by an erasure X-ray generation member which ionizes the air on the photosensitive layer, in which a coloring fine particle remains, upon irradiation of an X-ray emitted from within the substrate drum through the substrate drum and the photosensitive layer, while generating a carrier within the photosensitive layer.
