摘要： A developing device includes a developing member to carry developer stored by a developing frame, and a regulating blade having a support plate fixed to the developing frame, a plate-like member, and a regulating member. One end portion of the plate-like member is opposed to the developing member, and the other end portion is welded to the support plate. The regulating member is fixed to a plate-like member surface, and contacts the developing member to regulate a developer thickness on a developing surface. The regulating member is provided with a recessed portion recessed at a regulating member end portion. The regulating member end portion is lower than a regulating member central portion. A plate-like member region welded to the support plate is located at the plate-like member other end portion and overlaps the regulating member central portion and the regulating member end portion at which the recessed portion is provided.

摘要： A developing apparatus for use in an image forming apparatus includes a developing frame, a rotatable developing member, a regulation blade to regulate developer borne on a developing member surface, and a seal member to prevent developer from leaking outside the developing frame. The regulation blade includes a support plate, a plate-shaped member, and a regulation member. The seal member is fixed to a facing surface of the plate-shaped member, is arranged at a plate-shaped member end portion, is arranged side by side with the regulation member in a rotational axis direction, contacts an end surface of the regulation member, and is disposed between the plate-shaped member and the developing member in a direction intersecting with the rotational axis direction. The plate-shaped member is welded to a region of the support plate excluding a region outside the end surface of the regulation member in the rotational axis direction.
