Abstract
An image forming apparatus includes a developing unit, a transfer unit, a power source unit configured to supply a developing bias voltage to the developing unit and a transfer bias voltage to the transfer unit, and an input device to receive an image density evaluation. A processor adjusts the developing bias voltage when an evaluation input indicating a defect in the image density is received. If, after the first adjustment, another evaluation input indicating a defect in image density is received, the processor adjusts one of the developing bias voltage, the transfer bias voltage, or the toner density in the developing unit.
