ABSTRACT:
A uniformly electrostatically charged recording element is toned uniformly with magnetic toner particles and exposed simultaneously with both an image exposure and a separate flood light while the recording element is disposed in a magnetic field. The flood light is directed toward the uniformly toned (photoconductive) surface of the recording element while the image exposure is directed preferably onto the opposite (light-transmitting substrate) surface of the recording element.
