PURPOSE:To use an a-Si to make a copy possible, by using the a-Si, which has electric resistance increased by irradiation of light and has fatigue effects, for a photosensitive layer to form a copy image. CONSTITUTION:A photosensitive layer L consisting of an a-Si which has electric resistance increased by irradiation of light and has fatigue effects is formed on the outside circumferential face of a conductive drum S consisting of Al or the like to constitute a photoreceptor 1. While rotating the photoreceptor 1, the exposure of an original image is performed with an energy higher than a degree, where the electric resistance of the photosensitive layer L is increased and remains as fatigue, by an exposure mechanism 2. Electrostatic charge is given to the photosensitive layer L by a corona charger 3. Electric charge is held only in parts, where the electric resistance is increased to form an electrostatic charged image. This electrostatic charged image is inverted and developed with a toner by a developing equipment 4. The toner image is transferred to transfer paper or the like. When the photosensitive layer L is heated by a heater 8 and is irradiated with infrared rays of an infrared-ray lamp 9, it is recovered from fatigue. Thus, the a-Si is used to perform the copy. |
