Abstract
A printing system using a recharge, expose and development image on image process color system is disclosed in which there is an optional extra black development step. The printing system may be a single pass system where all of the colors are developed in a single pass or a multi-pass system where each color is developed in a separate pass. The additional black development step results in optimal color quality with black toner being developed in a first and/or last sequence. Having more than one black development station allows low gloss and high gloss black toner to be applied to the same image, enabling the very desirable combination of low gloss text and high gloss pictorials on the same page.
