1. An image forming apparatus comprising:
a first circuit configured to output a first voltage;
an image forming unit configured to form an image on a printing material using the first voltage;
a controller configured to control a value of the first voltage output by the first circuit according to a control signal; and
a storage unit configured to store control information of the first circuit,
wherein the control signal is a pulse signal,
wherein the controller controls, by controlling the frequency of the control signal, whether to set the value of the first voltage output by the first circuit to a first value or to a second value that is different from the first value, and
wherein the controller uses the control signal for communication with the storage unit.
