ELECTROPHOTOGRAPHIC COPIER

摘要

An electrophotographic copier comprises a photosensitive belt supported on first and second rollers and driven thereby, a development unit, a single transfer corotron, and an exposure unit. The development unit is disposed adjacent to the first roller, and the single transfer corotron is positioned on one side of a line connecting the first and second rollers, while the exposure unit is positioned on the other side of the line. The corotron charges the photosensitive belt during a first rotation of the belt around the rollers and causes transfer of a developed image from the photosensitive surface of the belt during a second rotation of the belt around the rollers.
