PROBLEM TO BE SOLVED: To provide a small-sized cleaning device capable of effectively recovering toner on a belt member, and an image forming apparatus using this cleaning device. SOLUTION: The cleaning device includes a belt member 1 which is stretched around a plurality of stretching member 2 and is cyclically moved, a rotating brush 3 which is brought into contact with the belt member 1 to clean off the toner on the belt member 1, a counter member 4 which is disposed so as to face the rotating brush 3 with the belt member 1 between them, and a bias applying means 5 capable of applying a cleaning bias between the rotating brush 3 and the counter member 4. A width in a belt member conveyance direction of a counter member contact area (A) brought into contact with the belt member 1 is narrower than that of a rotating brush contact area (B) brought into contact with the belt member 1, and the counter member contact area (A) is disposed off to an exit side in a rotating brush rotation direction of the rotating brush contact area (B), and two contact areas overlap at least partially.
