ABSTRACT:
A system for transferring charged toner in an electrostatic printing apparatus from a photoreceptive drum to a paper web comprises a flexible dielectric belt tensioned across the surface of the drum and having an integral flexible electrode facing the paper web which is located between the dielectric belt and the photoreceptive drum. The electrode is biased by a power supply such that the toner particles are forced by an electrostatic field away from the drum and onto the paper web. Additional flexible electrodes are used to control the electric fields at the leading and trailing edges of the zone of contact between the paper web and the drum.
