PROBLEM TO BE SOLVED: To provide a longer life to a device by rotating a photoreceptor drum at every constant interval of time in the wait state of printing and preventing the photoreceptor drum and a transfer belt from being left in contact with each other always on the same position for a long time. SOLUTION: In a transfer part 33, the transfer belt 3 is always pressed against the photoreceptor drum 5. A control part 20 rotates the photoreceptor drum 5 by a minute angle θ1 at every constant interval of time in the wait state of printing. Therein, after the photoreceptor drum 5 makes a revolution, the minute angle θ1 is selected in such a manner that the same place is not brought into contact with the transfer belt 3. |
