Abstract: An apparatus for improving the developability of a magnetic brush developing system by providing an electrically neutral entrance and exit flow region through which developer material passes as it enters and leaves the development zone. A second mode of operation is also provided for enhancing the system''s ability to develop input images of relatively low density.
