Abstract
A charging apparatus includes a charging member arranged to be adjacent to a photoconductive member with a gap having a tolerance in a charging region relative to the photoconductive member and applied with a voltage including a direct current voltage under a constant voltage control including an alternating current element to apply a charge to the photoconductive member. The alternating current element has a peak-to-peak voltage at least twice as great as a charge-start voltage to be applied to the charging member at a maximum gap within a range of the gap having the tolerance.
