An image forming apparatus comprises a plurality of photoconductors, a plurality of chargers including charging members, a voltage application unit to which charging members are connected in parallel and which is configured to apply a voltage to the charging members, a controller, and a messaging unit. The controller is configured to change, upon startup, the voltage to be applied by the voltage application unit to the charging members from a previously applied first voltage to a second voltage of which an absolute value is smaller than that of the first voltage, to obtain amounts of electric currents caused to flow through the respective charging members by application of the second voltage. A determination as to whether any anomaly is present is made based upon the obtained amounts of electric currents for the charging members. The messaging unit is configured to produce a notification about presence or absence of anomaly.
