Abstract

A developing device is provided which has a developing chamber, a toner container and a hopper portion all provided together on a revolving holding mechanism. A drive device is provided to revolve the driving mechanism and a stopping device is provided to stop this holding mechanism revolving movement at least to provide the developing chamber in a facing relationship to an image carrier. Moreover, the relative position of the toner chamber and the hopper portion are such that the hopper portion can be replenished with toner from the toner chamber at least once during a complete rotation of the revolving holding mechanism. Replenishment can occur independently of image formation, while the holding mechanism is revolving or during a pause in the revolving of the holding mechanism.
