Claims

[Claims for Utility Model Registration] 1. A motor that is driven based on a cleaning command, a winding member that is rotatably provided at one end of the motor, and a feeding member that is integrally or separately provided with the winding member and that is also provided at one end. a pulley provided at the other end; a charge wire that is pulled out from the feeding member, stretched, hung on the pulley, folded back, stretched again, and then wound around the winding member; and a charge wire that urges the pulley in a direction in which the charge wire is stretched. A corona discharger comprising: a biasing member; and a cleaning member pressed against the charge wire. 2. A forward/reverse drive motor is used as the motor, and a motor stopping means is provided to detect a motor lock and stop the motor, and the motor stopping means stops the motor and stops the motor when a post-cleaning command is received. The corona discharger according to claim 1, further comprising control means for reversely driving the corona discharger.
