摘要： A developing device is provided with developing unit covers mounted on opening portions of developing units through which developing rollers are exposed to close the opening portions. Due to such a construction, even when the developing units receive the vibration or the impact of falling during the course of transportation of an image forming apparatus on which the developing device is mounted, the overflow of a developer through the opening portion can be prevented.

摘要： A rotary developing device which facilitates a positional adjustment of developing units and prevents the developing units from being shifted even when they are used for a long period. Pins protruding from a revolver are inserted into elongated holes formed in developing units so that developing units are held in such a manner that the developing units are movable relative to the revolver. By mounting a spacer between the elongated hole and the pin, the positional adjustment of the photosensitive drum and the tracking roller is completed. Furthermore, a plurality of spacers which differ in thickness are prepared and by merely selectively mounting an appropriate spacer, the position adjustment of the tracking roller is completed.
