Abstract
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.
