Abstract:
Provided is a developing apparatus including a developer carrying member, a developer container, and a regulating member to regulate the thickness of the developer. The regulating member includes a support member such that one end is fixed to the developer container, the other end is a free end, and the support member extends in a direction opposite to the rotating direction of the developer carrying member, and a contact member to be fixed to the other end of the support member and to contact the developer carrying member. The contact member includes a contact curved surface along a peripheral surface of the developer carrying member, and an opposite surface to face the developer carrying member. The contact pressure of the contact curved surface applied to the developer carrying member decreases as a location on the developer carrying member approaches downstream side in the rotating direction.

Claim (Index 5):
The developing apparatus according to  claim 1 , wherein, when the developer carrying member is viewed in the rotation axis direction, a relationship between a radius Rb of an arc formed by at least a part of the contact curved surface and a radius Rd of the surface of the developer carrying member is satisfied with\n Rb>Rd, and a center Pb of a virtual circle, along which the contact curved surface extends, exists in regions (i), (ii) and (iii) defined below: Region (i), which is a region including a virtual straight line Ltp and an area located at an upstream side of the virtual straight line Ltp in the rotating direction of the developer carrying member, and the virtual straight line Ltp passes through a center Pd of the developer carrying member and a point Te; Region (ii), which is a region including a virtual circle Cp and an area outside the virtual circle Cp, and the virtual circle Cp is such a circle that (1) a center thereof is the point Te and (2) a radius thereof is the radius Rb; and Region (iii), which is a region including such a virtual straight line that (1) passes through the center Pd and (2) forms an angle with the virtual straight line Ltp, and the angle falls in 0\u00b0 and 45\u00b0, wherein the point Te is a point located at a most upstream position of the contact curved surface in the rotating direction of the developer carrying member.
