摘要: The present invention uses a scavengeless development system in which toner detachment from donor and the concomitant generation of controlled powder cloud is obtained by AC electric fields supplied self-spaced electrode structures positioned within nip. structure placed close proximity to toned gap between image receiver, self-spacing being effected via on donor. Such spacing enables creation relatively large electrostatic without risk air breakdown.
