Abstract
An image forming apparatus includes: an image bearing member; a toner image forming portion; a transfer member; a power source configured to apply a voltage to the transfer member so that a level of the voltage in a non-sheet-passing period in which a recording material is not in a transfer position is the same as that in a preceding sheet-passing period in which the recording material is in the transfer position; a current detecting member configured to detect a current flowing through the transfer member; and a controller configured to correct the voltage applied by the power source for the subsequent sheet-passing period on the basis of the detected current by the current detecting member in the non-sheet-passing period so that a predetermined current flows through the transfer member in the sheet-passing period.
