Abstract: PROBLEM TO BE SOLVED: To reduce the deflection of a developer carrier, without increasing the cost by reversing the directions of the deflections of the developer carrier caused by loads applied from each of a developing regulating member and a developer supplying roller to the developer carrier. SOLUTION: A supplying roller 21BR applies a radial load FRr and frictional force FRs in the tangential direction of a roller to a developing roller 21BS. A developing blade 21BB applies a radial load FBr and frictional force FBs in the tangential direction of the roller to the developing roller 21BS, as well.

Filed: 1978-03-02
Abstract: PURPOSE: To prevent loosening of connection by fixing locking ring which is supported by the impeller and the liner ring with the multi number of convexed parts into which the inner peripheral fringe of the locking ring is bent.  
     CONSTITUTION: The locking ring 1 is inserted between the liner ring 2 and the impeller 3. The appropriate number of locking convexes 20, 30 are cut in the inner peripheral part of the liner ring 2 and the suction side end inner peripheral of the impeller 3 so that the inner peripheral of the ring 1 is bent into the convexed parts 20, 30. Since the outward bending piece 12 is engaged in the liner ring groove 20, the liner ring 2 and the locking ring 1 do not rotate. Also, as the inward bending piece 13 is engaged in the convex part 30 of the impeller, the relative rotation of the locking ring 1 and the impeller 3 can be prevented. Therefore, the rotation of the liner ring 2 relative to the impeller 3 is prevented.
