PURPOSE:To equalize a picture density of the center and both ends without being influenced by a variance of a stretching force of a photosensitive body, or a temperature and a humidity, by constituting so that the photosensitive body is made to contact by pressure by the stretching plate. CONSTITUTION:A belt-like photosensitive body 1 is stretched by a large diameter roller 2, a small diameter roller 3 and a stretching plate 5. The photosensitive body 1 is charged electrostatically by an electrifier 8, exposed by a light passing through a condensing optical transmitting member 12, and developed by a developing tank 6. A transfer paper 9 is fed to a transfer part through a carrying roller 10, superposed at the same speed to the photosensitive body 1 depressed downward by the stretching plate 5, and moved to the left direction. When it moves to a position detached from the stretching plate 5, a toner is transferred to the transfer paper 9 by a discharger 4 for a transfer. Thereafter, the transfer paper 9 is peeled off naturally by the small diameter roller 3, and carried to a fixing part 11. The photosensitive body 1 is destaticized by a destaticizing discharger 7, cleaned by the developing device 6 used as a cleaning device, too, and reused. |
