Abstract
A cleaning apparatus is for removing a toner from a surface of an endless belt. The cleaning apparatus includes a blade, a blade holding structure, and an abutment maintaining structure. The blade abuts on the endless belt that is supported on a tension roller. The blade holding structure holds the blade with its rotation restricted, in a movable manner in the direction of motion adjustment to adjust tension on the endless belt, and causes the blade to abut on a winding area of the endless belt with respect to the tension roller. The abutment maintaining structure allows the blade to follow up movement of the tension roller to thereby maintain abutment of the blade on the endless belt.
