Abstract
An electrographic printing apparatus comprises a photoconductive member surrounded by a charging unit, an optical print head, a developing unit, a transfer unit, a cleaning unit, and an erasing unit arranged in sequence about the photoconductive member. Paper travels along a planar path across the top of the photoconductive member and the developed image is transferred to the underside of the paper. In a preferred embodiment, the photoconductive member comprises a vertically mounted photoconductive belt. By providing a separate and independent cleaning unit, the electrographic printing apparatus is capable of producing one sheet of copy material per revolution of the belt.
