An embodiment of a developing device may include a housing, magnetic developer, and a developer bearing member. In some embodiments, the developer bearing member may include a magnet member. The magnet member may allow the developer to remain in the housing. A developer regulating member may be positioned proximate the developer bearing member and have one or more cut portions. In some embodiments, the cut portions may be positioned at each end of the developer regulating member in a surface facing the developer bearing member. The developer regulating member may regulate an amount of the developer held on the developer bearing member. A magnetic sealing member may extend along an outer peripheral surface of the developer bearing member at each end and may be positioned proximate the cut portion. In some embodiments, a portion of the magnetic sealing member may be positioned within the cut portion.
