This photoreceptor cleaning member 1 may be substituted in a conventional copier cleaning housing with air flow as is presently used for brush or foam roll cleaners. The element 1 would be rotated against the photoreceptor in rotating arbors,

The cleaning member 1 consists of a rigid supporting core 2 and a compressible material 3 such as a foam around the core which flexibly supports the cleaning surface 4. The cleaning surface 4 is a flexible, non-porous skin which has integral flexible ribs 5 along the full length of the element 1. The core 2 is positioned relative to the photoreceptor so that the material 2 supporting the cleaning surface 4 is compressed by the photoreceptor. The cleaning surface 4 material is chosen to give the desired nip width and pressure. The ribs 5 provide the wiping and flicking actions necessary to remove toner from the photoreceptor surface, The dislodged toner is then carried away by the cleaner air flow,

The ribs 5 provide an advantage over brushes and foam rolls since they line contact the entire width of the photoreceptor surface rather than contacting many discrete points across the width, The element 1 may, therefore, rotate at slower speeds and
