PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of easily performing a discharge wire height adjusting operation of a corona charger in a short time without requiring a skill in determining an adjusting amount. SOLUTION: An image forming apparatus includes: an adjusting device for adjusting a distance from the discharging wire 21 to a photosensitive member; a detecting device for detecting information corresponding to a surface potential of the photosensitive member at least two points, along a longitudinal direction of the corona charger 2, in an area in which the photosensitive member is charged by the corona charger 2; and an executing device for executing an adjusting mode in which a reference mark Mo for positioning the sheet at a reference part 22 extending along a longitudinal direction of the corona charger 2 and an adjusting mark Mh for adjusting the distance from the charging wire 21 to the photosensitive member over the longitudinal direction of the corona charger 2 on the basis of an output of the detecting device are formed on the sheet P.
