ABSTRACT:
The present invention is concerned with a developer removing device for a copying apparatus. An electrostatic latent image is developer by a magnetic brush developing using a developer mix of magnetic carriers of small diameter and insulative non-magnetic toner charged to polarity opposite to one another and in which some of the magnetic carriers are transferred onto the background portion of the latent image. The developer removing device has a structure for removing the magnetic carriers adhering to the background portion at least either by magnetic force or electrostatic force.
