An image forming apparatus includes: a transfer member, a controller, a discharge electrode, a detector, and a storage section. The controller, based on an amount of change between parameter value detected by the detector after transfer by the transfer member and parameter value stored in the storage section, determines voltage necessary for the discharge electrode to take the same amount of current as an increase in transfer current of the transfer member from previously determined transfer current and applies the determined voltage to the discharge electrode.
