Abstract
With respect to a rotational direction of a rotatable developing member of a developing device, an opposing position where a regulating portion of the developing device is opposed to an outer peripheral surface of the rotatable developing member is between a first maximum position and a position where a magnetic flux density of a regulating pole in a tangential direction relative to the outer peripheral surface of the rotatable developing member is zero. With respect to the rotational direction of the rotatable developing member, the position where the magnetic flux density of the regulating pole in the tangential direction relative to the outer peripheral surface of the rotatable developing member is zero is within a range of ±2° of a midpoint between the first maximum position and a second maximum position or is downstream of the range.
