1. An image forming apparatus, comprising:
an image forming portion configured to apply a bias voltage in which an AC component is superimposed on a DC component between a first carrying member and a second carrying member, and to transfer toner from the first carrying member to the second carrying member to form an image on the second carrying member;
an AC setting processing portion configured to perform AC calibration to set a magnitude of the AC component of the bias voltage;
a potential measurement processing portion configured to measure a surface potential of the first carrying member or the second carrying member based on a target current flowing between the first carrying member and the second carrying member; and
a drive processing portion configured to execute the AC calibration before measurement of the surface potential in a case where, when measuring the surface potential, an activation condition is satisfied.
