摘要：An image forming apparatus includes an image carrying member, anintermediate transfer member, a charger, a transfer mechanism, a discharger, a directcurrent (d.c.) voltage source, and a d.c. voltage controller. The intermediate transfermember faces and contacts the image carrying member carrying a toner image, andreceives the toner image therefrom during a first transfer. The charger charges theintermediate transfer member to cause an electric field around where the image carryingmember and the intermediate transfer member contact each other, the electric fieldinitiating the first transfer. The transfer mechanism transfers the toner image from theintermediate transfer member to a transfer sheet. The discharger discharges chargeremaining on the intermediate transfer member. The d.c. voltage source applies a d.c.voltage to the discharger to cause the discharging. The d.c. voltage controller controlsthe d.c. voltage in accordance with a volume resistivity of the intermediate transfermember.
