摘要： A cleaning device and an image forming apparatus capable of suppressing staying of toner in a brush and reducing stress on a brush by discharge products are provided. A cleaning device includes upstream and downstream cleaning brushes and a cleaning roller, which respectively contact the surface of a secondary transfer belt, and first to third bias applying sections. The first bias applying section applies a bias voltage having a polarity opposite to that of the normal toner to the upstream cleaning brush. The second bias applying section applies a bias voltage having a polarity opposite to that of the normal toner and set to be not less than the absolute value of the bias voltage applied to the upstream cleaning brush, to the downstream cleaning brush. The third bias applying section applies a bias voltage having the same polarity as that of the normal toner to the cleaning roller.
