Abstract
A developing device according to the present disclosure includes a developer container, a duct, a duct coupling portion and a handle portion, and is removable with respect to an image forming apparatus. The duct is formed in the developer container and sucks floating toner together with air within the developer container. The duct coupling portion is formed at an end of the duct and is coupled to a toner suction portion of the image forming apparatus. The handle portion is formed in the shape of a flat plate and is formed to protrude from immediately below the duct coupling portion in a horizontal direction. A hollow portion is formed within the handle portion. A through hole is formed in a portion of an upper surface of the handle portion that is protruded as compared with an opening surface of the duct coupling portion and communicates with the hollow portion.
