PURPOSE: To provide an image forming device excellent in durability and safety, without adversely affecting the environment in use. CONSTITUTION: In the image forming device constituted in such a manner that a photosensitive layer 14 is provided on the outside surface of a freely rotatable closed loop-like substrate drum 13 and an electrifying means 11, an exposure unit 2, a developing unit 3, a transfer unit 4, a fixing unit 5 and a cleaning means 12 are provided around the substrate drum 13, it is composed of lightweight elements and the electrifying means 11 is composed of an electrifying X-ray generator means which is provided in the drum 13 and passes X-rays through the drum 13 and the photosensitive layer 14, to irradiate them, so that the air on the surface of the layer 14 is ionized and an electric field applying means for leading a gas ion generated by the ionization to the surface of the layer 14 by an electric field. Further, the cleaning means 12 is composed of an erasing X-ray generator means which ionizes the air on the photosensitive layer on which coloring fine grains remain with the irradiation with the X-rays transmitting the drum 13 and the layer 14, from the inside of the drum 13 and generates carriers in the layer 14. |
