PROBLEM TO BE SOLVED: To prevent transfer failure by optimally controlling the current, necessary for transfer and flowing in a photoreceptive drum. SOLUTION: The device has a current detection part 123, for detecting the value 12 of a current flowing in the photoreceptive drum 5, which is provided between the ground and the point of connection between the ground-side terminal of the secondary windings of a separation transformer 111 provided in a separation circuit 11 and the ground-side terminal of the secondary windings of a transfer transformer 121 provided in a transfer circuit 12. The device also has in the transfer circuit 12 a control part 122 for controlling a transfer output based on a detection signal from the current detection part 123. |
