A powder accommodation container includes an accommodation container body, a regulation member, and a transport member. The accommodation container body has a hole portion to outside and accommodates powder. The regulation member is provided in the hole portion to regulate a passage of the powder accommodated in the accommodation container body. The transport member is arranged in an inside of the accommodation container body to rotate about a rotating shaft and to transport the powder in the inside of the accommodation container body. The transport member has one end side in a short direction that is arranged on the rotating shaft and the other end side that is a free end, the free end includes a flexible member that is in contact with the accommodation container body to be flexed. The flexible member is locatable to face the hole portion.

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.

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.
