Abstract
An image forming apparatus includes an image carrier configured to carry an image and a charger to which a direct current voltage overlapped with an AC voltage is applied as a charging bias to charge the image carrier. The charger is positioned in contact or contactlessly with the image carrier. A controller performs an adjustment to the AC voltage multiple times to gradually bring the AC voltage to a target value.
