Definitions

  • Electrophoretic charging of a photoconductive member 2 is accomplished by applying a potential from source 32 between a conductive backing 6 on the photoconductive member and an electrode 24 spaced therefrom which acts upon charged transparent particles 14 dispersed in a dielectric liquid 12 therebetween.
  • the field which is created between the photoconductive member and the electrode causes the charged particles to be uniformly distributed across the photoconductive surface 4 which surface may then be subjected to further electrophotographic procedures.
