Further, the control memberis arranged to be in parallel with a developing rollerin an axial direction of a magnet fixing shaft. The control memberis such a non-magnetic member that the nearest part of the non-magnetic member from the developing rollerhas been caused to be ferromagnetic and has been magnetic-field oriented.
