Summary:An absolute value of a first maximum value is less than that of an absolute value of a second maximum value. In regards to a rotation direction of a rotatable developing member, an angle at which the magnetic flux density of a regulating pole in a direction normal to an outer circumferential surface of the rotatable developing member from the second maximum position becomes a half value of the second maximum value from the downstream side of a second maximum position is smaller than an angle at which the magnetic flux density of the regulating pole in a direction normal to the outer circumferential surface of the rotatable developing member becomes a half value of the first maxim value on the upstream side of the first maximum position to the first maximum value. A developing device comprises: a developing container; a developing member; a magnet; and a regulation part. 제1 최대값의 절대값은 제2 최대값의 절대값보다 작다. 회전가능한 현상 부재의 회전 방향에 관해서, 제2 최대 위치로부터 회전가능한 현상 부재의 외주면에 대한 법선 방향에서의 규제 극의 자속 밀도가 제2 최대 위치의 하류 측에서 제2 최대값의 반값이 되는 위치까지의 각도는, 회전가능한 현상 부재의 외주면에 대한 법선 방향에서의 규제 극의 자속 밀도가 제1 최대 위치의 상류 측에서 제1 최대값의 반값이 되는 위치로부터 제1 최대값까지의 각도보다 작다.
