Patent ID: 8879941

Claim:
A cleaning device, comprising: an upstream cleaning brush that contacts a surface of a moving body to which toner adheres; a downstream cleaning brush that is arranged on a downstream side of the upstream cleaning brush in a moving direction of the moving body and that contacts a surface of the moving body; a cleaning roller that is arranged on a downstream side of the downstream cleaning brush in a moving direction of the moving body and that contacts a surface of the moving body; a first bias applying section that applies a bias voltage having a polarity opposite to that of normal toner to the upstream cleaning brush; a second bias applying section that applies a bias voltage to the downstream cleaning brush, the bias voltage having a polarity opposite to that of normal toner and being set to be not less than an absolute value of a bias voltage applied to the upstream cleaning brush; and a third bias applying section that applies a bias voltage having the same polarity as that of normal toner to the cleaning roller.
