摘要
A two-pass light/lens highlight color copier in which high contrast images are created providing relatively large development fields or potentials compared to those associated with tri-level imaging. The imaging system disclosed has a conventional light lens imaging or exposure station, one Charged Area Development (CAD) subsystem including positively charged black toner, and one CAD scavengeless development subsystem including a positively charged highlight color toner. Other subsystems normally found in the xerographic imaging environment, such as charging, exposure, transfer and fusing are also employed. A high contrast CAD image is formed in the first pass using conventional Light/Lens scanning optics. A spectral filter is used with the Light/Lens optics during a second pass for forming a highlight color image.
