ABSTRACT:
An electrophotographic copying apparatus includes a copying cycle which always alternates development between two image areas to equalize wear along the length of its photosensitive belt and which eliminates a cleaning cycle after the final copy of a copying cycle to reduce belt revolutions. Also included is a combined charger/precleaner to reduce size and a light image mask to prevent unnecessary toning of the belt.
