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

In one embodiment, the charging voltage supply is arranged to provide a pulsed-voltage waveform. In one variation of this embodiment, the pulsed-voltage waveform comprises a pulsed-DC waveform. In another embodiment, the charging voltage supply is arranged to provide an alternating-current waveform. In one embodiment, the charging device itself is comprised in an image forming device.
