Abstract

Reducing the effective coefficient of friction between a cleaning blade and the photoreceptor surface is proposed by vibrating the blade in a plane normal the photorecep~ tor surface, to provide reduced and intermittent average contact area and force therebetween. Vibration at a frequency of about 10 kilohertz to achieve a wave length along the blade, (i.e., a distance between blade contact points) in the order of 10 microns is suggested. The amplitude of the vibration of the blade tip normal the photoreceptor should not exceed about one micron in order to maintain a cleaning seal gap between the blade and the photoreceptor which is smaller than the dimensions of the toner being removed.
