Abstract

PURPOSE:To operate a warning means corresponding to the operation of a detecting means of eletecting the amount of a developer and another detecting mans of supplying the developer in a preparatory container to a developing container on the detection of the former detecting means and then detecting the supplemented developer, by providing the said detecting means to the containers wherein the developer is contained. CONSTITUTION:When a developer 2 in a developing container 1 decreases and an actuator 13a turns on a switch 13, a pump 6 is put in operation to supply a developer 3 in a preparatory container 2 to the container 1. At this time, a switch 25 operates to set a timer 17. The set time T of the timer 17 is little longer than the time from the operation of the pump to the operation of a pressure switch 25 by the developer in the preparatory tank 4. This timer stops the pump 6 when the container 4 is emptied. When an actuator 12b turns on a switch 14, the 2nd warning signal is generated and a developing device is stopped.
