PROBLEM TO BE SOLVED: To provide an image forming apparatus that can prevent the occurrence of toner fogging.SOLUTION: An image forming apparatus 100 includes charging units (preliminary charging device 216 and charging device 212) that charge the surface of a photoreceptor drum 211 to a charging polarity of toner, detection units (detection unit 190 and control unit 200) that detect toner fogging in a non-paper feed area on the surface of the photoreceptor drum 211, and the control unit 200 that controls, when toner fogging is detected by the detection units, the charging units to increase the charging potential in the non-paper feed area. |
