Abstract
An apparatus for cleaning an endless photosensitive surface includes a photoreceptor rotatable around a horizontal axis in an electrophotographic copying machine. A cleaning roller and an edge of a blade are maintained in frictional engagement with the upper run of the rotating surface and into the space between the roller and the blade, a cleaning liquid is continuously supplied onto the surface between the blade edge and the cleaning roller, thereby achieving an effective cleaning function. The liquid within the space tending to flow over the other edge of the blade remote from the photosensitive surface and to then drip on the cleaned surface, is effectively prevented in accordance with the invention.
