Abstract:
An image forming apparatus includes a heating member which heats a recording material on which an unfixed toner image has been formed, a pressurizing member which forms a nip portion between the heating member and the pressurizing member and applies pressure to press the recording material against the heating member in the nip portion, and a controller which applies a voltage, which has a polarity opposite to the polarity of the surface potential of the charged pressurizing member and a predetermined voltage value with which electric discharge does not occur between a hole in a surface layer of the pressurizing member and the heating member, to the heating member to remove electricity from the surface layer of the pressurizing member when the recording material is not present in the nip portion.
