Figure 1 is a partial isometric schematic view of an improved residual toner removing cleaning blade assembly 10 mounted adjacent a photoreceptor 11. Figure 2 is a schematic side view of the cleaning blade assembly. In Figures 1 and 2, the cleaning blade 13 and mounting bar 12 are adhered to opposite sides of the foam pad 14. The function of the foam pad is to compensate for system tolerances which, without the pad, would tend to cause the cleaner blade not to ride uniformly along the axial length of the photoreceptor surface 16. The mounting bar serves to (1) attach the cleaner blade and foam pad to the sub-system structure (not shown), (2) contribute to the establishment of the common blade-photoreceptor angle, and (3) apply the predetermined blade pressure against the photoreceptor surface. The foam pad provides means for the assembly to (1) expand or compress to compensate for photoreceptor drum or belt runout, inboard-outboard eccentricity, and the like, (2) compensate for variance in mounting bar position, and (3) dampen blade chatter.
