PURPOSE:To observe the inside of a suction duct and to easily clean the inside of the suction duct by providing a suction opening formed widely and a lid freely openable, and also providing the suction duct which is arranged as a different body from a developing device. CONSTITUTION:The suction duct 3 has the suction opening 4 formed widely in the width direction of the axis of a photosensitive drum opposite to the photosensitive drum 1, the lid 5 which can be opened and closed freely, and a duct main body 8, and the duct is provided as a different body from the developing device 2. Then a suction motor as a sucking means sucks developer clouds from the suction opening 4, so the motor is provided behind the suction duct 3 (Suction port is the front.). Consequently, the lid is opened and closed without detaching the developing device, so developer clouds can easily be cleaned. |
