摘要 |
A developing device includes first and second developing members facing an image bearing member and respectively having substantially-cylindrical first and second sleeves rotationally driven in a circumferential direction and first and second magnet rollers fixedly supported within the first and second sleeves and provided with magnetic poles in the circumferential direction; a supply member supplying a two-component developer onto the first sleeve; a layer regulating member facing the first sleeve and regulating a layer of the two-component developer thereon; and a magnetic member facing the second sleeve with a certain distance therebetween at a position facing a magnetic pole provided downstream of a development pole and upstream of a removal pole, which are included in the magnetic poles of the second magnet roller, in a rotational direction of the second sleeve. The development pole faces the image bearing member. The removal pole removes the two-component developer from the second sleeve.
