PURPOSE:To provide an image forming device of the reversal developing system capable of obtaining the excellent image without a transfer defect, even in the image forming succeeding to the image forming when jamming occurs. CONSTITUTION:At the time of detecting the stagnating jam by a second sensor 13 and at the time of detecting the jamming by a third sensor 14, as the image forming has been performed and the transferring material P is located between the second and the third sensors 13 and 14, the toner image on the photosensitive drum 1 is partially or fully affected by the corona discharge of the transferring, therefore the toner scattering is increased and the soiling of the transferring electrifier 4 is increased. Then, the soiling of the transferring electifier 4 is removed by actuating the cleaner 41, thus, the excellent image without the transfer defect is obtained in the following image forming. |
