Abstract
A corona generating device for depositing negative charge on an 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 absorbing nitrogen oxide species generated once the corona generating 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. 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 substantially continuous thin conductive dry film of aluminum hydroxide.
