Abstract
In an axial direction of a developing sleeve that bears magnetic developer on an outer circumferential surface thereof, ends of a sheet-shaped stirring member that stirs the magnetic developer in a container frame to move the magnetic developer toward the developing sleeve are disposed on an outer side of a region in a magnetic field region generated by a magnet roller disposed on an inner side of the developing sleeve. The region has a magnetic field strength equal to or larger than a predetermined magnetic flux density at which the magnetic developer can be borne on the surface of the developing sleeve.
