摘要： An image forming apparatus includes an image carrying member, an intermediate transfer member, a charging member, a transfer mechanism, a discharging member, a direct current voltage source, and a direct current voltage controller. The intermediate transfer member is deposited at a position facing and in contact with the image carrying member rotatably carrying a toner image on a rotating surface, and receives the toner image therefrom during a first transfer operation. The charging member applies a charge to the intermediate transfer member to cause an electric field around a region where the image carrying member and the intermediate transfer member contact with each other, where the electric field generates a force for initiating the first transfer operation. The transfer mechanism performs a second transfer operation for transferring the toner image from the intermediate transfer member to a transfer sheet. The discharging member performs a discharging operation for discharging the charge remaining on the intermediate transfer member with contacting the intermediate transfer member after a completion of the second transfer operation. The direct current voltage source applies a direct current voltage to the discharging member to cause the discharging member to perform the discharging operation. The direct current voltage controller controls the direct current voltage in accordance with a volume resistivity of the intermediate transfer member.

摘要： An image forming apparatus includes an image carrying member, intermediate transfer member, charger, transfer mechanism, discharger, direct current voltage source, and direct current voltage controller. The intermediate transfer member contacts the image carrying member and receives a toner image therefrom during a first transfer operation. The charger charges the intermediate transfer member to generate an electric field where the image carrying member and the intermediate transfer member contact each other for initiating the first transfer operation. The transfer mechanism performs a second transfer operation to transfer the toner image from the intermediate transfer member to a transfer sheet. The discharger discharges a charge remaining on the intermediate transfer member after completing the second transfer operation by the direct current voltage source applying a direct current voltage to the discharger. The direct current voltage controller controls the direct current voltage based on a volume resistivity of the intermediate transfer member.
