摘要： A developing device, process cartridge method, and image forming apparatus for developing an electrostatic latent image on an image carrier, the developing device including a first carrying member that supplies a developer to a developer carrier at the position of a developer attracting fourth magnetic pole while longitudinally carrying the developer, and a second carrying member that carries the developer released from the developer carrier at the position of a developer releasing third magnetic pole. The developer carrier has two magnetic poles (second and fourth magnetic poles) of the same polarity sandwiching the developer releasing third magnetic pole. Moreover, the developer releasing third magnetic pole is formed by the two magnetic poles (second and fourth magnetic poles) so that the polarity of the developer releasing third magnetic pole differs from the polarity of the two magnetic poles (second and fourth magnetic poles).
