PROBLEM TO BE SOLVED: To provide an image forming device whose cleaning time is shortened by making the cleaning time of a transfer member optimized at the jamming occurring time or the abnormal stopping time of the device. SOLUTION: This image forming device, provided with cleaning means for performing a cleaning of a transfer roller 14a by applying an electric field in the direction opposite to the electric field for development between a photoreceptor drum 10 and the transfer roller 14a, and provided with a dot number counter for counting the number of dots at the working time of performing the image exposure. When transport defect of transfer material P occurs, the cleaning of the transfer roller 14a by the above cleaning means is performed at the recovering time. The device decides the cleaning time for performing the cleaning in accordance with the number of dots counted by the above dot number counter. |
