Abstract
Single Pass Highlight Color (SPHLC) and Single Pass Custom Color (SPCC) images are made possible on a single print using relatively high development fields compared to the prior art. Three scavengeless development housings, one with the specified custom color toner, one with a highlight color toner, and one with black toner (or another color desired for non-highlight images) are utilized. The black development system has toner of one polarity, for example, positive. The two color systems both use negatively charged toner. Alternatively, the black toner may be negatively charged in which case the custom and highlight color toners would be positively charged.
