ABSTRACT:
A corona generating device for depositing negative charge on the imaging surface carried on a conductive substrate comprises at least one elongated conductive corona discharge electrode, means to connect the electrode to a corona generating potential source, at least one element adjacent the corona discharge electrode capable of adsorbing nitrogen oxide species generated when the electrode is energized and capable of desorbing nitrogen oxide species once that electrode is not energized, the element being coated with a substantially continuous thin conductive dry film of aluminum hydroxide containing graphite and powdered nickel. In a preferred embodiment, the conductive corona discharge electrode comprises a scorotron with at least one linear array of pin coronodes where the corona control grid is coated with the film.
