Abstract
A charging apparatus includes a charging member for charging a member to be charged; voltage application means for applying an oscillating voltage to the charging member; current detecting means for detecting an electric currant flowing through the charging member; time detecting means for detecting time during which an output level of the current detecting means; and voltage control means for controlling an oscillating component of the voltage applied to the charging member on the basis of an output of the time detecting means.
