ABSTRACT:
A single component development system utilizing insulative nonmagnetic toner. A toner mover transports toner from a supply of toner for transfer to a donor roll from which it is deposited on to latent electrostatic images contained on an imaging surface. An electrically biased flap of conductive material is supported for rubbing contact with the surface of the toner mover. Supporting the electrically biased, conductive flap in rubbing contact with the toner mover results in effective reloading of the doner roll notwithstanding the presence a high stress condition such as the requirement for developing images containing conditnuous solid areas.
