ABSTRACT:
A scavengeless or non-interactive development system is described for use in image formation such as highlight color imaging. A toned donor roll structure having two sets of interdigitated electrodes physically supported by an insulative support structure is provided. An equal magnitude DC potential is applied to both sets of electrodes while an AC potential is applied to either one or both sets of electrodes. The AC and DC biases are such as to preclude background development without creating fringe DC fields between adjacent electrodes.
