摘要： A wire cleaning device has a cleaner movable for cleaning a charging wire in a corona discharger, and a motor for moving the cleaner. Whether or not the cleaner is locked somewhat in its stroke of movement is determined by signals from a position detector and a movement failure detector, or signals from an overcurrent detector and a timer. Alternatively, the cleaner which is locked in its moving stroke is forcibly moved by a larger amount of energy than normal, or is vibrated, on the basis of signals from a home position sensor and a failure detector.
