IPC: G03G15/16
Filed: 1989-09-14
Abstract: PURPOSE:To prevent generation of back soiling of a following print by storing this when jamming generates and impressing reverse bias on a transfer roll before starting of printing when the device is started after jamming processing. CONSTITUTION:When jamming is detected by a jamming detecting means that is, a paper feeding sensor 14 or a paper ejecting sensor 15, provided in a transfer material passage, is it stored in a non volatile memory 18 by the CPU 16, and after a door is opened and the jamming processing is carried out, the state before the door is released is read out from the non volatile memory 18 by the CPU. Then when the action of the device is restarted, by impressing the reverse bias on the transfer roll 3 at a specified time for a specified time, toner of a photosensitive body 5 can be prevented from sticking on the transfer roll 3 at the time of jamming, and toner sticking on the transfer roll 3 is transferred to the photosensitive body 5 side and the toner can be eliminated by a destaticizing needle 4. Thus, the soiling of the back of the transfer material can be automatically prevented from being generated.
