Abstract of the DisclosureProcess for eliminating the need for a separatecleaning station in a one-cycle electophotographicdocument copier machine of the transfer type. Abackcharge corona generator is added to provide anovercharge/backcharge process to obtain the desiredlevel of charge on the photoconductive system priorto exposure of the photoreceptor to the subject. Inthat manner, residual toner remaining on the photo-conductor after production of the previous copy iscleaned simultaneously with the development of thesucceeding copy.B0979032
