Abstract
A cleaning unit for a xerographic printing machine, or the like. A system for mechanically or electrostatically removing objects, such a toner or paper particles in a printing machine from a photoreceptor or other member to be cleaned, includes a cleaning brush rotating in contact with the member to be cleaned, a cleaning roll brought into contact with the cleaning brush to electrostatically or magnetically remove toner from the cleaning brush, and a cleaning blade supported at the base by a blade holder. The cleaning blade is pressed against the cleaning roll, to remove toner deposited on the surface of the cleaning roll. The cleaning blade is a resilient, thin metal plate.
