Original Abstract Submitted

a developing device includes a first rotatable member; a first magnet including a first magnetic pole, a second magnetic pole, and a third magnetic pole identical in polarity to the second magnetic pole; a second rotatable member; and a second magnet including a fourth magnetic pole different in polarity from and closest to the second magnetic pole, a fifth magnetic pole, and a sixth magnetic pole identical in polarity to the fifth magnetic pole. in a rotational direction of the second rotatable member, a maximum magnetic flux density position of the fourth magnetic pole of the second magnet in a normal direction relative to an outer peripheral surface of the second rotatable member is positioned downstream of the closest position of the second rotatable member to the first rotatable member on the outer peripheral surface of the second rotatable member, and is positioned upstream of the fifth magnetic pole.
