ABSTRACT:
An apparatus for cleaning the imaging surface of an electrophotographic machine that includes a biased conductive foam roll. The biased conductive foam roll removes toner from the photoreceptor. The biased foam roll provides the electrostatic cleaning advantages of an electrostatic brush cleaner without the problem of toner accumulation in the brush. The cell structure of the foam roll limits toner accumulation to close to the cleaning surface to enable simple detoning of the foam roll cleaner by a biased detoning roll or air flow.
