PURPOSE:To extend the life of a blade and obtain stably copy pictures of high quality by using a photosensitive sheet consisting of an organic photoconductor. CONSTITUTION:A photosensitive band 5 is carried by a pair of carrying rolls 5a and 5b simultaneously with copy start, and an electrostatic charge charger 9 starts electrostatic charge, and the light of an exposure lamp 10a of an exposure device 10 is reflected on the surface of an original and is formed as an electrostatic latent image on the photosensitive band 5. A developing roll 14 is driven to control the gap between a developing sleeve 13a of a developing device 17 and the photosensitive body 5, and a visible image is formed by a toner. A copy paper 18 is supplied from a paper supply cassette 17 onto the toner image on the photosensitive body 5, and the toner image is transferred by a transfer charger 15. The photosensitive body 5 after transfer is advanced furthermore, and the remaining toner is removed by a cleaning device 27, and the remaining electric charge is removed by a destaticizing lamp 28, and the photosensitive body 5 is returned to the original arrangement position in a photosensitive body cassette 4 and is held between a pair of carrying rolls 5a and 5b, thus completing the copying operation. |
