Abstract
A control unit can execute regulation control referred to as active transfer voltage control (ATVC) for setting a transfer voltage output from a second voltage unit to a transfer member so as to transfer a toner image from a photosensitive member to a transfer material based on an electric current value detected by a detection unit and a voltage value output from a voltage output unit. When changing a voltage value output from the voltage output unit during execution of the ATVC, the control unit interrupts execution of a predetermined operation of the ATVC in a predetermined time period including a point of time including when the voltage output from the voltage output unit is changed.
