A method and apparatus applicable to electrophotographic image forming equipment or similar equipment for positioning a corona discharger relative to a photoconductive element. Two charge currents caused to flow through axially opposite end portions of the photoconductive element by a corona discharger are detected, and their difference is determined. The inclination of a discharge electrode included in the corona discharger relative to the photoconductive element is so adjusted as to reduce the difference to zero.
