ABSTRACT:
The inventive developing apparatus 10 includes: a developing roller 15 rotating in a predetermined direction; a regulating blade 16 for regulating layer thickness of developer G1 on the developer roller; 15; and a supplying roller 17 disposed at the upper stream than the regulating blade 16 while the developing apparatus 10 rotates in the predetermined direction. Further, the developing apparatus 10 rotates the developing roller 15 in the reverse direction for the predetermined direction during a predetermined period. Thereby, agglomerates stopping at the space between the developing roller 15 and the regulating blade 16 escape therefrom and developer leak and defective supply of developer and the like are cleared away. While the developing roller 15 is rotated in the reverse direction, the agglomerates escaped from the space come to contact with the supplying roller 17 and are crashed by press of the developing roller 15 and the supplying roller 17. As a result, agglomerates escaped from the space between the regulating blade 16 and the developing roller 15 is prevented from stopping therebetween again and accumulating in developer.
