Abstract
An image forming apparatus includes a high voltage generating circuitthat applies an oscillating voltage in which a DC voltage and an AC voltage are superimposed on each other, to a charging memberdisposed in contact with an image carrier; a voltage control portionthat controls a peak-to-peak voltage of the AC voltage to a target voltage value; and an initial voltage adjusting portionthat sets a target voltage value based on a DC current value between the image carrierand the charging memberwhich is detected by a current detecting portion. When an environmental condition which is used when the target voltage value is set changes, the initial voltage adjusting portionperforms an interrupt operation during an image forming process.
