ABSTRACT:
An image forming apparatus including an intermediate transfer member, an image forming device for forming a toner image on the intermediate transfer member wherein the toner image on the intermediate transfer member is transferred to a transfer material, a charging member for charging the intermediate transfer member by contacting the intermediate transfer member, wherein discharge is performed between the charging member and the intermediate transfer member by a voltage in which the direct current voltage and the alternating current voltage are superimposed applied to the charging member when the intermediate transfer member is charged by the charging member, and a control device for controlling the voltage applied to the charging member, wherein the control device stops the supply of the alternating current voltage to the charging member after the peak-to-peak voltage applied to the charging member is attenuated.
