Abstract
An apparatus for cleaning residual toner and debris from a moving charge retentive surface of an image forming apparatus includes a multiple turret style blade holder located such that an individual blade is selectively indexed into optimum position for cleaning the moving photoreceptor. The blade holder contains a number of cleaning blades mounted radially from a central core and by rotating the holder about its longitudinal axis a specified number of degrees (360.degree./number of cleaning blades on the holder) a new cleaning blade is moved by the indexing device into the cleaning position to replace a failed blade. The indexing device removes the failed cleaning blade and positions a new cleaning blade in frictional contact with the photoreceptor for cleaning.
