ABSTRACT:
In a copying apparatus where image developer material is cleaned from a reusable imaging surface by a resilient cleaning blade, one edge of the blade is mounted within a blade retaining channel with opposing generally parallel walls spaced apart by a distance slightly greater than the thickness of the blade to provide unobstructed ingress of the cleaning blade mounting edge against a linear base of the channel without compression of the blade. The blade mounting channel has an arcuate intermediate bend resiliently bending the cleaning blade within the channel sufficiently to cause the cleaning blade to resiliently frictionally engage both walls of the channel to frictionally retain the blade and to seal the channel from the image developer material.
