ABSTRACT:
A two cycle electrophotographic copying apparatus includes an operatively rotatable photosensitive body, an electric charging device, a cleaning lamp disposed upstream of the charging device, and a neutralizing electrode disposed downstream of the charging device. This novel arrangement of the cleaning lamp and neutralizing electrode results in a significantly reduced occurrence of toner contamination by residual electric field attraction to operating and structural portions of the copying apparatus which are positioned about the photosensitive body.
