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.

Two-cycle electrophotographic copying apparatus in which a cleaning lamp

A system for adjusting the output current of a discharge electrode for electrophotographic copying machines comprising the step of adjusting the output current of the discharge electrode in the electrophotographic copying machine by selecting a selector switch which corresponds to a class of photosensitive members, such that the discharge electrode produces an output current which is suited for the photosensitive members of the class.
