ABSTRACT:
In a development device for developing an electrostatic latent image formed on an image bearing body, the development device includes: a developer bearing body for conveying a developer borne thereon to a developing area on the image bearing body; a plurality of magnetic poles provided inside the developer bearing body; a detaching magnetic pole including optional two adjoining poles of the plurality of magnetic poles which are arranged to have the same polarity as each other for forming a repulsive magnetic field to remove the developer on the developer bearing body; and a magnetic body provided in the vicinity of and spaced away from the detaching magnetic pole, for forming a repulsive magnetic field having the same polarity as that of the detaching magnetic pole.
