PROBLEM TO BE SOLVED: To provide an image forming device making the toner container possible to be set on a position parting from the developing device, and moreover letting the toner replenishment possible to be surely performed while maintaining the toner quality. SOLUTION: This image forming device is letting air supplied in the toner container 20 by the air pump 30, letting the toner being contained in the toner container 20 stored in the receiving part 91 on this side of a screw pump 80 transited to the developing device by sifting the toner outside the container 20, making the stored toner quantity sensed by the level sensor 100, and the toner transited to the developing device based on the detection signal of this sensor. |
