Abstract

An improved apparatus is provided for cleaning the discharge electrode or electrodes of a corona generating device. The apparatus includes a cleaning element which is adapted to traverse the operative length of the electrode. An edge of the cleaning element engages the electrode to provide an effective scraping action on the surface thereof to clean the debris such as dust particles and toner particles therefrom. Preferably, the element cocks in operation to provide a first edge for scraping the electrode when the element is traversed in a first direction and a second edge for scraping the electrode when the element is traversed in an opposing direction. Preferably, the cleaning element also includes means for cleaning the shield of the corona generator. An electrostatographic reproducing apparatus incorporating the aforenoted cleaning apparatus also forms part of the instant invention.
