摘要：An image forming apparatus includes an image carrying member, an

intermediate transfer member, a charging member, a transfer mechanism, a dischargingmember, a direct current voltage source, and a direct current voltage controller. Theintermediate transfer member is deposited at a position facing and in contact with theimage carrying member rotatably carrying a toner image on a rotating surface, andreceives the toner image therefrom during a first transfer operation. The chargingmember applies a charge to the intermediate transfer member to cause an electric fieldaround a region where the image carrying member and the intermediate transfermember contact with each other, where the electric field generates a force for initiatingthe first transfer operation. The transfer mechanism performs a second transferoperation for transferring the toner image from the intermediate transfer member to atransfer sheet. The discharging member performs a discharging operation for

discharging the charge remaining on the intermediate transfer member with contactingthe intermediate transfer member after a completion of the second transfer operation.The direct current voltage source applies a direct current voltage to the dischargingmember to cause the discharging member to perform the discharging operation. Thedirect current voltage controller controls the direct current voltage in accordance with avolume resistivity of the intermediate transfer member.
