<p>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 (14) is disposed on the outer surface of a closed-loop substrate drum (13) which is rotatable, while charge means (11), an exposure portion, a developing portion, a transfer portion, a fixing portion, and cleaning means (12) are provided around the substrate drum. The charge means (11) is constituted by charging X-ray generation means, which electrolytically dissociates the air on the surface of the photosensitive layer (14) upon irradiation with an X-ray, and electric-field application means (16a,16b) 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 means (12) is constituted by erasure X-ray generation means (12a) which ionizes the air on the photosensitive layer, in which a coloring fine particle remains, upon irradiation with an X-ray irradiation, while generating a carrier within the photosensitive layer.</p> |
