Multiple cleaning blade indexing apparatus.

摘要

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 (10) located such that an individual blade is selectively indexed into optimum position for cleaning the moving photoreceptor. The blade holder (10) contains a number of cleaning blades mounted radially from a central core and by rotating the holder (10) about its longitudinal axis a specified number of degrees (360 DEG /number of cleaning blades on the holder) a new cleaning blade is moved by the indexing device (35,41,42,44,46) 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. <IMAGE>
