Abstract

In a copying apparatus 10 where image developer material is cleaned from a reusable imaging surface 12 by a resilient cleaning blade 16, one edge 18 of the blade is mounted within a blade retaining channel 24 of a blade holder 22 with opposing generally parallel walls 30, 32 spaced apart by distance slightly greater than the thickness of the blade 16 to provide unobstructed ingress 26 of the cleaning blade mounting edge up to a linear base 28 of the channel 24 without compression of the blade. The blade mounting channel 24 has an arcuate intermediate bend 34 resiliently bending the cleaning blade 16 within the channel 24 sufficiently to cause the cleaning blade to resiliently frictionally engage both walls 30 and 32 of the channel 24 to frictionally retain the blade and to seal the channel at 36 and 38 from the image developer material.
