摘要 |
A magnetic brush type developing device using a one-component system developing agent suitable for use with electrophotographic copying apparatus including a scraper having a magnetic wire disposed in close proximity to a developing sleeve serving as means for agitating and mixing a developing agent used for developing and a fresh supply of the developing agent fed to supplement the developing agent consumed by developing. The scraper includes a nonmagnetic plate provided with a plurality of stays in the form of a comb disposed on a side thereof facing the developing sleeve, and a magnetic wire mounted on the forward end of the stays and arranged in a magnetic field generated by a magnet disposed in the developing sleeve. The magnetic wire and the developing sleeve are spaced apart from each other by a predetermined gap.
