Abstract
A developing apparatus includes a developer carrying member, a developing frame member to rotatably supporting the developer carrying member, and a regulating member provided on the developing frame member and regulating developer carried on the developer carrying member. The regulating member includes a projecting part projected towards the developer carrying member and having an abutting part that abuts the developer carrying member, and an opposing surface facing the developer carrying member. The opposing surface is positioned on an upstream side of the projecting part and arranged to connect the projecting part with a distal end of the regulating member at a free end side of the regulating member. In addition, the opposing surface is a surface having no point of reverse curve, and the distance between the opposing surface and the developer carrying member is constant or decreasing with distance from the projecting part.
