ABSTRACT:
A toner near empty discriminating unit discriminates a near empty indicating that the toner approaches an empty state on the basis of a detection value of a toner sensor. When the toner near empty is determined, a toner supply amount calculating unit calculates a toner supply amount (w) per time as w=W/X from the number (X) of toner supplying times of a toner supply counter and a specified toner filling amount (W) when a toner cartridge is set. On the basis of the calculated toner supply amount (w) of one time, a correction processing unit corrects a rotational speed of a supply roller of a toner supply control unit and an operation time of the supply roller, or the number of discriminating times of the toner empty and the number of discriminating times of a replacement of an expendable item.
