Abstract
PURPOSE:To improve the detection accuracy and control accuracy of a discharging current for transfer by removing a leakage current from the detection signal of a current monitor detecting circuit. CONSTITUTION:A chute provided to a transfer device is connected behind the discharging current monitor detecting circuit 7 through a high resistance. In this case, the chute 4 may be connected to a corotron shield 3 through the high resistance as shown by a solid line and connected behind the monitor detecting circuit 7 from the corotron shield 3, or connected directly behind the discharging current monitor detecting circuit 7 through the high resistance separately from the corotron shield 3 as shown by a dotted line. Here, the leakage current flowing to the chute 4 flows to the rear stage of the current discharging current monitor detecting circuit 7. Consequently, the discharging current is monitored and controlled properly.
