Patent ID: 8811863

Claim:
A developing device comprising: a developing member including a magnetism generating member having a plurality of magnetic poles polarized in a circumferential direction thereof, and a rotating member that is rotated about the magnetism generating member while holding a developer on a surface thereof, the developing member supplying a toner included in the developer to an image carrier on which an electrostatic latent image is formed to develop the electrostatic latent image; a developer pumping pole that is provided in the magnetism generating member, and that pumps up the developer, which is supplied from a developer accommodating portion accommodating the developer, to the surface of the rotating member; a developer peeling-off pole that is provided in the magnetism generating member below a rotation axis of the rotating member in a vertical direction on an upstream side of the developer pumping pole in a rotational direction of the rotating member, and that peels off the developer from the surface of the rotating member; and a magnetic body comprising one of a magnet or a member that is magnetized by the developer peeling-off pole, wherein the magnetic body is arranged relative to the developer peeling-off pole so as to form an attractive magnetic field between the magnetic body and the developer peeling-off pole, and wherein the magnetic body is completely and directly provided between a facing position facing the developer peeling-off pole in a circumferential direction of the rotating member and a facing position facing the developer pumping pole in the circumferential direction, and that faces the surface of the rotating member.
