Abstract
1275822 Developing electrostatic images RANK XEROX Ltd 21 May 1969 [28 May 1968] 26014/69 Heading G2H An apparatus for developing an electrostatic image on a xerographic belt 12 comprises a belt 55 of electrically conductive material passing around cylinders 57 and 59 of non-magnetic material. A fixed permanent magnet 71 loads developer 53 comprising electroscopic toner and magnetic carrier particles on to the belt 55 from a trough, while a magnet 85 causes release of such developer at the opposite end of the belt. One or more magnets 101 are rotated beneath the upper run of the belt 55 to create a rotating magnetic field to form developer into a wave form on the belt 55. A D. C. potential 102, e.g. between 125 and 175 volts is applied to the belt 55 to improve solid area development and reduce background.
