Abstract
A rotary developing device for an image forming apparatus includes a plurality of rotary developing units accommodating a powder developer and being supported around a common axis, and a plurality of toner cartridges corresponding to the plurality of rotary developing units for supplying toner to the plurality of rotary developing units. Each rotary developing unit is moved to a developing position facing a latent image carrier by the rotation about the common axis and an electrostatic latent image formed on the latent image carrier is developed. The plurality of toner cartridges are connected with the plurality of rotary developing units so as to rotate together, and a toner outlet of the toner cartridge is disposed such that the toner is supplied to the respective rotary developing unit by the force of gravity on the toner accommodated in the respective toner cartridge at the time of rotational movement of the toner cartridge.
