摘要： Method and apparatus for cleaning a residual toner powder image bearing surface after transfer of substantially all of a charged toner image therefrom to a support member. Fans or air pumps are utilized to direct a flow of ionized air to the surface to be cleaned. The ionized air is directed to the surface and neutralizes any charge on the residual particles remaining on the surface after image transfer to allow the particles to be readily removed. The ionization is produced by corona discharge, and illuminating means may also be included.

摘要： An applicator for uniformly applying magnetically responsive dry particulate material to broad areas on a web moved past the applicator to deposit the material in pattern areas attracting the material thereto. The applicator comprises an applicating roller having a plurality of magnetic members arranged about a shaft within a rotatable non-magnetic sleeve to provide a magnetic field around the roller having a feed zone with a radial field changing to a tangential field, an applicating zone with a stronger radial field following the feed zone and a return zone extending from the applicating zone to the feed zone and having a stronger tangential field immediately following the applicating zone. A scavenging roller has a plurality of magnetic members arranged about a rotatable shaft within a non-magnetic sleeve to carry any free particulate material applied by the applicating roller away from the web surface and back to a tray.

摘要： This invention relates to an electroded cascade development system wherein an extended electrically conductive electrode plate is closely spaced from a xerographic surface being developed. The xerographic surface is moved in an uphill direction against the direction flow of the cascading developer. The electrode is completely insulated electrically from its surrounding whereby it is electrically floating with respect to ground and the image bearing surface for improved development of latent electrostatic images developed under its influence.

摘要： Build-up of undesired potential on the blocking electrode in a photoelectrophoretic imaging system during successive imaging operations is prevented by one of several methods. Typically, potential of a sign opposite to that built up may be applied, or the blocking electrode surface may be discharged between imaging cycles.
