A pre-c1ean toner agglomerate dispersing foam roll 1 may be added to a 4000 or other blade cleaning copier, One way is by removing the pre-clean corotron and installing a small diam-eter, but relatively large pore foam rubber cylindrical roller 1 extending the width of the photoreceptor 2 mounted in the corotron end mounting brackets (on Teflon end bearings, or the like) This places the foam roller forcibly engaging the entire drum 2 surface width just upstream of the toner clean-ing blade 3. The foam roll I is preferably rotated only by its frictional contact with the drum 2 surface. A contact arc of approximately 1/2fl of contact between the foam roll and the drum surface has been found to be sufficient to provide the
