An image forming apparatus includes an image carrying member, an intermediate transfer member, a charger, a transfer mechanism, a discharger, a direct current (d.c.) voltage source, and a d.c. voltage controller. The intermediate transfer member faces and contacts the image carrying member carrying a toner image, and receives the toner image therefrom during a first transfer. The charger charges the intermediate transfer member to cause an electric field around where the image carrying member and the intermediate transfer member contact each other, the electric field initiating the first transfer. The transfer mechanism transfers the toner image from the intermediate transfer member to a transfer sheet. The discharger discharges charge remaining 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 controls the d.c. voltage in accordance with a volume resistivity of the intermediate transfer member.
