摘要：A single-component development system utilizing insulative nonmagnetic toner(44) uses a toner mover (80) to transport toner from a supply of toner to a donor roll(42) from which it is deposited on to latent electrostatic images on an imaging surface(18). An electrically-biased flap (82) of conductive material is supported in rubbingcontact with the surface of the toner mover. The flap results in effective reloading of thedonor roll notwithstanding the removal of toner therefrom at a high rate, such as whendeveloping images containing continuous-solid areas.
