PROBLEM TO BE SOLVED: To improve image quality by preventing the occurrence of a lateral white streak or the like which results from an irregularity in the residual potential of an intermediate transfer body. SOLUTION: Before the transfer of a toner image to the intermediate transfer body from a photoreceptor (primary transfer) or after the transfer of the toner image to transfer paper from the intermediate transfer body (secondary transfer), the intermediate transfer body is electrified by an electrifying means to make residual potential uniform, thereby eliminating the irregularity. A corona discharger 454 as a transfer means used for transferring the toner image to the transfer paper from the intermediate transfer belt 426, as the intermediate transfer body, is also used as an electrifying means. By using the corona discharger 454, the intermediate transfer belt 426, when the toner image does not exist, is electrified and, thus, the potential is made uniform. |
