Abstract
PURPOSE:To maintain high quality over a long period by stopping a transfer electrifier, an electrifier and a destaticizing lamp in that order when transfer ends. CONSTITUTION:When the tailing edge of a transfer sheet passes by the transfer electrifier 6, its function is stopped at that timing t1. Then the function of the electrifier 2 is stopped at a timing t2, that is, a time (b) (ms) passes when a photosensitive body 1 rotates exceeding the arranging and rotating angle of the transfer electrifier 6 and the electrifier 2. Therefore a part which is positively electrified is canceled with the negative electrification of the electrifier 2. Next, the function of the destaticizing lamp 9 is stopped at a timing t3, that is, a time (a) (ms) passes when the photosensitive body 1 makes one or more turns. Thus electric charges in the part which is positively electrified are completely canceled.
