Abstract
An image forming apparatus has an image carrier, a charger, a developing device, a voltage application unit, and a controller. The developing device includes a developing roller. The voltage application unit applies a voltage to the developing roller and to the charger. The controller controls the voltage application unit. The controller controls the voltage application unit such that a developing bias having an AC voltage superposed on a DC voltage is applied to the developing roller and a charging bias including at least a DC voltage and having superposed thereon a compensation AC voltage with an opposite phase to an AC voltage induced in the charger by the developing bias is applied to the charger.
