Disclosed is a magnetic brush configuration, which permits developer conductivity to range over a wide latitude. The configuration is comprised of a conventional magnetic brush roller 1, which develops the bulk of-the electrostatic latent image on the photoreceptor 4, particularly solid areas, a field-free magnetic brush 2, which develops gradients thereby enhancing low-density lines, and a pick-off element 3, which scavages carrier beads that may be left by the field-free magnetic brush.
