Abstract
According to an embodiment of the invention, a revolver unit is rotationally driven by using three stepping motors. The weight of developing cartridges loaded on the revolver unit is identified on the basis of the quantity of remaining toner in toner cartridges. At the time of rotationally driving the revolver unit, output timing of the stepping motor closer to the developing cartridge which has a large quantity of remaining toner and has a heavy weight is made earlier, and output timing of the stepping motor far from this developing cartridge is delayed.
