ABSTRACT:
A multi-color imaging apparatus utilizing recharging between two image creation steps for recharging a charge retentive surface to a predetermined potential prior to forming a second of the two images. The two images are formed using toner particles which are subject to under color splatter (UCS). The UCS phenomena occurs when a developed image passes through a toner cloud created by a certain type of scavengeless development system. The forgoing problem is obviated by applying pressure to toner images in combination with recharging thereof prior to their passage through a developer housing.
