ABSTRACT:
Disclosed is an image forming apparatus capable of elongating the service life of an intermediate transfer belt and of performing cleaning on the intermediate transfer belt in a satisfactory manner. To remove any residual toner on a second intermediate transfer belt, a cleaning blade is brought into contact with the second intermediate transfer belt, and a voltage is applied to the cleaning blade to thereby remove the residual toner and paper powder. In the case of one-side copying and when no residual toner exists on the second intermediate transfer belt, the cleaning blade is brought into contact with the second intermediate transfer belt to thereby remove paper powder.
