Abstract

In electrographic printing apparatus, a charge transfer endless-loop dielectric belt including a conductive member to effect a ground plant is supported to tension with an unsupported portion thereof disposed opposite the electrodes of the print head. The unsupported portion results from belt engagement with the printhead in regions adjacent to the electrodes to provide the desired electrode/dielectric belt spacing.
