Abstract
A control unit drives a driving unit for a correction driving time to supply toner to a developing unit from a toner supplying unit, when a detecting unit detects that an amount of toner stored in the developing unit is equal to or less than a threshold value. A calculating unit calculates an amount of toner consumption from when the toner is supplied to the developing unit to when the detecting unit detects that the amount of the toner stored in the developing unit is equal to or less than the threshold value. The control unit calculates a unit amount of toner supply from the correction driving time and the amount of toner consumption, and supplies the toner to the developing unit by driving the driving unit on the basis of the calculated unit amount of toner supply.
