Abstract: Voltages are applied to an image bearing member using at least three application voltage values which are larger than a discharge start voltage value and which have different magnitudes, at least one of the application voltage values having a value at which a direction of a current corresponding to the one of the application voltage values is reverse to those of currents corresponding to the other application voltage values. A relation between the application voltage value and the detection current value in a discharge area is calculated based on at least three application voltage values Vd1, Vd2, Vd3 and at least three detection current values Id1, Id2, Id3 detected by a current detection portion in relation to at least three application voltage values Vd1, Vd2, Vd3 and a voltage value V0 at which the detection current value is zero is calculated based on the relation in the discharge area.

When the surface potential is determined by the potential detection portion, the voltage application portion applies the detection voltage after applying, to the voltage application member, a voltage having an opposite polarity to an image formation voltage that is applied to the voltage application member during image formation.
