PROBLEM TO BE SOLVED: To form an image with high image quality and to prevent deterioration of developer and frictional scratches on a developing sleeve by removing image history which remains on the developing sleeve after development, and eliminating an image defect, called ghost, after the development. SOLUTION: The developing device has a magnetic-field generation member 148 which is disposed opposite the developing sleeve 141, intensifies a magnetic field near the surface of the developing sleeve 141 toward outside, and collects developer on the developing sleeve 141 by attracting it in such a manner as to peel it off the developing sleeve 141. The device also has a developer carrying member 144 which is disposed rotatably near the developing sleeve 141 and the magnetic-field generation member 148, and carries the developer, attracted and carried from the developing sleeve 141 by the magnetic-field generation member 148, to a developer storage part 140 so that the developer is not moved toward the developing sleeve 141. |
