An image forming apparatus includes: an image bearing member; a transfer portion; a first electrostatic cleaning portion including a first electroconductive member; a second electrostatic cleaning portion including a second electroconductive member; a first detecting portion for outputting first information corresponding to a first current passing through the first electroconductive member; a second detecting portion for outputting second information corresponding to a second current passing through the second electroconductive member; and a controller for controlling, based on the first information and the second information, a transfer voltage so that the voltage is decreased when a decrease amount of the first current is larger than that of the second current and so that the voltage is increased when the decrease amount of the second current is larger than that of the first current. |
