Abstract
An image forming unit forms a toner image on an image carrier, and transfers the toner image to a recording medium. A voltage generation circuit generates a high voltage used for the image forming unit. A control circuit is connected to the voltage generation circuit via a cable, and controls the high voltage generated by the voltage generation circuit. A detection unit detects a current flowing in a load of the image forming unit to which the high voltage generated by the voltage generation circuit is applied. A determination unit determines an error in accordance with a current range in which the current detected by the detection unit falls. The current range is included among a plurality of current ranges that are in one-to-one correspondence with a plurality of errors.
