ABSTRACT:
An image forming apparatus includes a high voltage generating circuit91that applies an oscillating voltage in which a DC voltage and an AC voltage are superimposed on each other, to a charging member42disposed in contact with an image carrier41; a voltage control portion96that controls a peak-to-peak voltage of the AC voltage to a target voltage value; and an initial voltage adjusting portion95that sets a target voltage value based on a DC current value between the image carrier41and the charging member42which is detected by a current detecting portion92. When an environmental condition which is used when the target voltage value is set changes, the initial voltage adjusting portion95performs an interrupt operation during an image forming process.
