Abstract
A method for charging an electrophotographic imaging surface includes the steps of reciprocating at least one longitudinally disposed corona electrode along the longitudinal axis and simultaneously applying a corona voltage to the electrode for developing a corona so that a substantially uniform corona charge is applied to the entire electrophotographic imaging surface. An additional step, performed simultaneously with production of the corona and reciprocation of the electrode can be the movement of one of the electrodes or the electrophotographic imaging surface relative to the other. Apparatus employed to perform this method also is disclosed.
