Claims

[Claims for Utility Model Registration] (1) A suction duct is provided on the outer wall surface of the device housing disposed opposite to the latent image carrier, and the suction duct is removably connected to the suction device. In a developing device that sucks and removes the developer that escapes from the gap between the suction duct and the image carrier, the suction duct and the suction device are attached to at least one of them, and when connected, the other side is attached to the suction duct and the suction device. A developing device characterized in that an elastic sealing member is provided that tightly contacts the connecting portion and closes the gap between the connecting portions. (2) Claims for registration of a utility model characterized in that the suction duct and the suction device are connected in a state of contact, and the elastic seal member closes the gap between the contact portions from the outside or the inside. Developing device according to item 1. (3) The above-mentioned suction duct and the suction device are connected in a fitted state, and the above-mentioned elastic seal member is interposed in this overlapping part to close the gap. Developing device according to item 1.
