ABSTRACT:
In an image forming apparatus such as an electrophotographic copying machine or an electrophotographic printer, for performing development by using a two-component developer, a carrier collecting device for collecting a carrier deposited on a photosensitive member in development is provided. The carrier collecting device includes a fixed magnet disposed in such a manner that an intermediate position between an S pole and an N pole of the fixed magnet is closest to the photosensitive member. Accordingly, the carrier can be effectively collected from the photosensitive member, and the carrier captured to the fixed magnet can be prevented from rubbing against the photosensitive member.
