PURPOSE:To prevent developer from dropping so as not to stain the inside of a device by forming an inner projection part which is made closer to a developer carrier on a part of a developer receiving part. CONSTITUTION:The developer receiving part 125b is formed on the aperture part of the edge of an upper casing 125 and the inner projection part 125c which is made closer to a developing sleeve 111A is formed on a part of the developer receiving part 125b. Since the developer which drops from a part where the developing sleeve 111A and the surface of a photosensitive drum 25 are close is received by the developer receiving part 125b and also the developer which moves to the direction of the aperture part with the carrier force and gravity from the carrying member is interrupted with an interruption effect by the inner projection part 125c and a magnetic roll 121A, it does not move to the developer receiving part 125b. Thus, the drops of developer from the aperture is removed, so that the stain of the inside of the device caused by the scatter of the developer can be prevented. |
