Abstract

An image-forming apparatus which does not adversely affect its surrounding environment when in use, which has excellent durability, and which is safe to use is provided. A photosensitive layer is disposed on the outer surface of a rotatable closed-loop substrate drum. A charger, an exposure portion, a developing portion, a transfer portion, a fixing portion, and a cleaner are provided around the substrate drum. The charger includes an X-ray generator, which electrolytically dissociates the air on the surface of the photosensitive layer upon X-ray irradiation, and electric-field generator which guides a gaseous ion formed by electrolytic dissociation to the surface of the photosensitive layer. The cleaner is constituted by erasure X-ray generation means 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.
