Abstract
A cleaning device according to the present invention comprises which includes a cleaning belt, an unwinder, a winder, and a detector. The unwinder is wound with the cleaning belt. The winder winds up the cleaning belt intermittently from the unwinder along a path leading past a cleaning position where the belt is brought into contact with a body to be cleaned. The detector is fitted in a detecting position on the path between the unwinder and the cleaning position. The cleaning belt has an end point set on it near its trailing end and associated with the detecting position. When detecting the end point, the detector outputs a detection signal.
