Abstract

PURPOSE:To improve operability by detecting a toner end, automatically selecting a developing unit containing developer in the same color, shifting and moving it to a developing position and replacing a cartridge or replenishing toner after an image forming process comes to an end. CONSTITUTION:Information on developing colors of the developing units 12a-12c in respective positions is stored. With the aid of signals detecting the toner end of the developing units 12a-12c in the developing position, information on the developing colors of the developing units 12a-12c lying in the developing position is compared with information on the developing colors of the developing units 12a-12c lying in the other positions. When information on the same developing color exists, the developing device 12 is rotated based on information on the positions of the corresponding developing units 12a-12c, and the corresponding developing units 12a-12c are switched to the developing position to continue the image forming process. After said process is terminated, the developing units 12a-12c which run out of toner are moved to a preset position, then a cartridge is replaced or replenishment of toner is executed. Thus operability is improved.
