Abstract

PURPOSE:To execute a control of a proper toner replenishment by executing a toner replenishment in accordance with a detected value of a level detecting means only in a prescribed replenishment period. CONSTITUTION:The titled controller is provided with a level detecting means 13 for detecting a developer level in a developing container 4, and a control means 14 for controlling an operation of a toner replenishing means 5 so that the replenishment is not executed in the stand-by time which has subtracted a prescribed replenishment time required for replenishing at least a necessary toner for the same copying, from its final period in a copying operation period to one sheet of copying paper, and the toner replenishment is executed in accordance with a detected value of the level detecting means 13 only in the same prescribed replenishment period. In such a way, at the stand-by time in the copying operation period to one sheet of transfer paper, even if the developer level is below at a prescribed time, no replenishment is executed, and thereafter, only at a prescribed replenishment time, a necessary toner replenishment is executed in accordance with the developer level, therefore, it does not occur that the toner is supplied excessively due to an erroneous decision, at an initial stage having the possibility that the developer sinks in.
