Abstract
A corona discharge arrangement for shifting the transfer point in a xerographic machine comprising an elongated wire and a shield having a plurality of conductive segments insulated from each other. A biasing arrangement is provided for changing the bias potentials on the various segments to effect a shift in the transfer point in response to preselected conditions. The transfer point may alternatively be maintained stationary by changes in the biasing potentials in response to changes in conditions which would otherwise result in a change in the transfer point.
