ABSTRACT:
A cleaning apparatus, electrostatographic machine and process are provided wherein particulate material is removed from the surface of an electrostatographic imaging member by at least one blade member having an edge engaging the surface. The blade edge is vibrated at a frequency sufficiently high to substantially reduce the frictional resistance between the blade edge and the imaging surface. The amplitude of the vibrations is controlled to a level which will insure sufficient conformity between the blade edge and the imaging surface so that adequate cleaning can be provided. Preferably the vibrations are carried out at ultrasonic frequencies with an amplitude less than about 0.005 inches.
