Summary:PROBLEM TO BE SOLVED: To collectively discharge the deteriorated developer, from plural developing units. SOLUTION: This device is provided with a discharging tube for concentratedly discharging the developer becoming in excess as a result of the developer newly replenished in the developing units 4Y, 4M, 4C and 4K, into the center shaft of the developing device assembly 4. The developer concentrated in the center shaft (in pipe shape) is transported to the shaft end through an auger disposed in the center shaft, allowed to fall in a connecting pipe 25 and join the connecting pipe 22. The connecting pipe 22 is the pipe for recovering the waste toner on a belt 5, and incorporate the auger. The waste toner and the deteriorated developer are recovered in a recovering box 17 through this connecting pipe 22.
