Abstract: CONTOL OF PHOTOCONDUCTOR CHARGE SOURCES TO FACILITATE PHOTOCONDUCTOR CLEANING DURING RUNOUT An electrophotographic copying apparatus having a triboelectrically charged brush cleaning station which interacts with toner to clean the photoconductor, and charging means operable during the runout cycle to charge drum carried foreign materials to the opposite polarity to that of the brush, such that the foreign materials are readily removed from the photoconductor by the cleaning station.
