A rotary developing device for color image forming equipment has a plurality of developing units around a common rotary shaft and rotates the developing units about the common shaft to bring any one of them to a developing position. A drive connecting and disconnecting device in the form of a clutch is provided integrally with each developing unit and sets up and interrupts drive transmission from a drive source to only one of the developing units.
