Abstract
An image forming apparatus is provided with a plurality of developing units in which the toner replenishing device equipped with each developing unit is actuated for a predetermined period of time. When toner replenishment cannot be completed at the time when the developing unit has stopped its action, it is arranged so as to either actuate the developing unit and the toner replenishing device for a predetermined time after image formation is carried out or keep the toner replenishing device in action after the developing unit has stopped its operation for a predetermined period of time while at the same time actuating the developing unit for the remaining time of the predetermined time after image formation is carried out.
