Abstract: Provided is an image forming apparatus that is capable of carrying out a scattered-toner recovery mode in which, while image formation is prevented from being performed, scattered toner that has dropped from a filter and adhered to an outer peripheral surface of a developer carrying member is recovered by a cleaning unit through intermediation of an image bearing member. A fixed magnet of the developer carrying member has a first pole that faces the image bearing member, a second pole that faces the filter, and an intermediate pole between the first pole and the second pole.

Abstract: A developing device includes a first agitating member and a second agitating member. Each of the first and second agitating members includes a screw having a helical portion formed helically so as to define a hollow portion, and a plurality of ribs formed on the helical portion in the longitudinal direction of the screw. On at least one of the first and second agitating members, there is disposed a paddle opposed to the communicating portion on a downstream side in a transport direction of the developing powder. The paddle has a flat surface in a direction perpendicular to the longitudinal direction, and a width of a distal end of the paddle is smaller than a width of a proximal end of the paddle disposed to the agitating member in a plan view.
