Abstract
After an application of a first AC voltage for selecting a peak-to-peak voltage of a charging AC voltage for charging an image forming area of an image bearing member and before an application of a charging AC voltage, there is applied a second AC voltage having a peak-to-peak voltage larger than a peak-to-peak voltage of the first AC voltage.
