A cleaning method applicable to a photoconductive element installed in an electrophotographic copier or similar image recorder of the type performing repetitive steps of charging, exposing, developing, transferring, discharging, cleaning and so forth. The method includes the steps of measuring the surface potential of the photoconductive element remaining after discharging which occurs prior to cleaning, comparing the measured potential with a reference potential, and controlling the output voltage of a discharging device to maintain the surface potential constant. |
