ABSTRACT:
An apparatus for enabling a conductive backed photoconductive intermediate transfer member in an electrophotographic printing apparatus with pre-charge and light assist. The printing apparatus includes a toner transfer system having an intermediate transfer belt comprising a highly conductive transparent substrate with a charging device and an illumination lamp. The intermediate transfer belt is pre-charged prior to entering a transfer nip region to generate low or reverse fields therein. Subsequently, the photoconductive layer of the intermediate surface is exposed to light energy to discharge the pre-charge thereon, generating high transfer fields in the transfer nip.
