ABSTRACT:
A cleaning device for an image forming apparatus, wherein a magnetic developer image formed on the surface of an endlessly moving image bearing member is transferred onto an image transfer member, which comprises: a cleaning device to remove the magnetic developer remaining on the surface of the image bearing member; a magnetic field forming source situated in the vicinity of the cleaning device to confine the magnetic developer; a magnetic developer absorbing device having a surface to lead the confined magnetic developer from the surface of the image bearing member to a position away from it; a separating and guiding device which separates the magnetic developer from the magnetic developer adsorbing device, and guides the same outside the confining magnetic field; and a developer conveying device which conveys the removed toner in the direction substantially orthogonal to the moving direction of the image bearing member at a position where the confining magnetic field does not extend substantially.
