Title of the Invention PHOTOCONDUCTIVE DRUM CLEANING APPARATUS Abstract of the Disclosure Apparatus for cleaning the photoconductive drum of an electrostatic copier in which a rotating foam roller and a self-cleaning squeegee blade are sequentially arranged adjacent the photoconductive surface at a location follow- ing the station at which the image has been transferred to copy material such as paper. The self-cleaning squeegee blade is formed by a driven endless belt which extends across the entire photoconductive surface and which is so disposed that an edge portion or portions contact the surface of the photoconductor. The endless belt is cleaned by means remote from the photoconductive surface. In various embodiments of the invention the endless belt contacts the photoconductive surface at an acute, a right, and an obtuse angle to a tangent to the photoconductive surface. Means is provided for supplying developer liquid to the developer applicator on start-up of the machine and to the cleaning apparatus upon initiation of a copying operation. To prevent scratching of the photoconductive surface by the cleaning apparatus, the cleaning apparatus is retracted from the photoconductive surface until such time after initiation of a copying operation that the -1- surface portion initially at the developer applicator has advanced to a position adjacent to the cleaning apparatus.
