Abstract

1373010 Magnetic brush developing XEROX CORP 13 Dec 1971 [14 Dec 1970] 57765/71 Heading G2H Electrostatic latent images on an upwardly moving, inclined surface 12 are developed by magnetic brushes 31-34, excess developer being returned to a sump 26 by gravity (preferably via a mixing baffle 62) and reapplied to the lowest brush 31 by a paddle wheel 46. A blade 60 doctors brush 31. Development may be quickly terminated by rotating the magnets forming the brushes.
