It has sometimes been the case that when a developing device becomes inverted with the rotation of a rotary, a developer in the developing device flows out in a great deal through a discharge port. So, the height of the ceiling of an agitating chamber is made great in an area near the discharge port, it has become possible to prevent the excessive discharge of the developer from the developing device.
