Abstract
An image forming apparatus includes a revolving member, a transfer member, a guide member, and a controller. The revolving member revolves and retains a toner image on a peripheral surface thereof. The transfer member nips a transported recording medium and the revolving member at a nipping section and transfers the toner image retained by the revolving member onto the recording medium by receiving a voltage. The guide member is connected to ground, guides the recording medium to the nipping section, and is in contact with the recording medium nipped at the nipping section. The controller performs constant current control to transfer the toner image onto the recording medium if a print resistance is lower than or equal to a system resistance. The print resistance corresponds to when the voltage is applied to the transfer member in a state where the recording medium is nipped at the nipping section. The system resistance corresponds to when the voltage is applied to the transfer member in a state where the recording medium is not nipped at the nipping section.
