A charging apparatus (21) includes a charging member (11), contactably provided to a member (10) to be charged; voltage application means (22,24-26) for applying different AC voltages to the charging member; and determination means (29,30) for determining when the different AC voltages are applied to a first area of the member to be charged a peak-to-peak voltage to be applied to a second area of the member to be charged, on the basis of a peak-to-peak voltage (V0) corresponding to a predetermined minimum current through the member to be charged.A charging apparatus (21) includes a charging member (11), contactably provided to a member (10) to be charged; voltage application means (22,24-26) for applying different AC voltages to the charging member; and determination means (29,30) for determining when the different AC voltages are applied to a first area of the member to be charged a peak-to-peak voltage to be applied to a second area of the member to be charged, on the basis of a peak-to-peak voltage (V0) corresponding to a predetermined minimum current through the member to be charged. <IMAGE>
