PURPOSE:To extend the life of a blade and obtain stably copy images of high quality by constituting a device so that a photosensitive sheet is recovered into the second box of a photosensitive body cassette and a fresh photosensitive sheet is taken out from the first box and is used when the former photosensitive sheet is degranded to reach the use limit. CONSTITUTION:By copy start, a photosensitive body 4 is charged electrostatically by an electrostatic charge charger 6, and simultaneously, an exposure device 7 is moved in the direction of an arrow. The light of an exposure lamp 7a is reflected on the surface of an original and is formed as an electrostatic latent image on the photosensitive body 4 through an optical fiber lens 7b. The gap between a developing sleeve 9a of a developing device 9 and the photosensitive body 4 is controlled to form a visible image with a toner. The photosensitive body after transfer is advanced furthermore, and the remaining toner is removed by a cleaning device 24, and the remaining electric charge is removed by a destaticizing lamp 25, and the photosensitive body 4 is carried by a pair of carrying rolls 26 and is returned to the original arrangement position and is held between a pair of photosensitive body holding rolls 5a and 5b, thus completing the copying operation. |
