Abstract

In order to extend the life of reusable photoconductors, effective cleaning is essential. Often times cleaning aides are introduced into the developer package to facilitate toner removals. These cleaning aides, in addition to toner resi-dues, can buildup on the recording surface of photoconductive members after extended use even with efficient cleaning systems being employed. In order to prevent such eventual buildup from occurring, it is suggested that the recording surface of the photoconductive member be periodically con-tacted with an abrasive element. Such abrasive elements can include woven mats or felts of alumina fibers or foam wipers impregnated with abrasive materials. The periodic treatment of the photoconductive element with such a device will prevent the undesirable buildup referred to hereinabove and thereby extend the useful life of the photoreceptor beyond that attainable in the absence of such a scavenging element.
