Abstract: An image forming apparatus has: an image supporting member, a charger, a power source unit, an amperometric detector, and a processor. The power source unit applies a plurality of charging voltages, which includes alternating voltages respectively, to the charger sequentially while no print medium is fed. The alternating voltages have different peak-to-peak voltages for a forward discharge range and different peak-to-peak voltages for a reverse discharge range, respectively. The amperometric detector detects values of alternating current flowing in the charger during application of the charging voltages. The processor derives characteristic lines of alternating current value with respect to alternating voltage for the forward discharge range and for the reverse discharge range, respectively, from the values detected by the amperometric detector. The processor derives a peak-to-peak voltage to be used in a process in a different way depending on a difference in slope between the characteristic lines.
