Abstract:
1. A method of producing an image on a final image receptor from image data in a multiple pass electrophotographic system, comprising the steps of: providing a photoreceptive element having a determined processing cycle; providing at least one development unit containing charged toner particles dispersed in a carrier liquid, wherein at least one of the photoreceptive element and each development unit are moved into a processing position relative to each other and performing the following steps (a) through (c) for each development unit during each complete processing cycle of the photoreceptive element; providing a transfer assist material development unit containing a liquid transfer assist material comprising charged particles; moving at least one of the photoreceptive element and the transfer assist material development unit into a processing position relative to each other and applying the transfer assist material to at least a portion of the toned image during the processing cycle of the photoreceptive element to form a composite image layer on the photoreceptive element; and contacting the composite image layer with a final image receptor while applying an electrostatic bias potential through the final image receptor that is sufficiently strong to transfer at least a portion of the composite image layer from the photoreceptive element to the final image receptor.
