Apparatur zur Tonerleilchenübertragung auf ein Substrat

An apparatus for enabling a laterally conductive, resistive backed photoconductive intermediate transfer member (28) in an electrophotographic printing apparatus. The printing apparatus includes a toner transfer system having an intermediate transfer belt (28) comprising a laterally conductive resistive substrate (60) with a pre-transfer grounding device (68) and a transfer charging device (66). A ground potential bias is applied to the intermediate transfer belt (28) prior to entering a transfer nip region to generate low transfer fields therein. Subsequently, the laterally conductive resistive layer (60) of the intermediate surface is provided with a biasing voltage, generating high transfer fields in the transfer nip. In an alternative embodiment, a post-transfer bias is applied to the intermediate transfer belt for substantially enhancing the transfer fields in the transfer nip.
