Abstract
An image forming apparatus includes a power supply circuit, at least one motor configured to receive electric power from the power supply circuit, a photosensitive body configured to be rotated by the motor for forming an image on a sheet, a charger configured to charge the photosensitive body, a high voltage generation circuit configured to receive electric power from the power supply circuit and generate a high voltage applied to the charger, and a control device. The control device is configured to determine whether a motor activation condition to activate the motor is satisfied, determine whether a limitation condition to limit a peak of a current output from the power supply circuit is satisfied, and regulate the current flowing through the high-voltage generation circuit if the motor activation condition and the limitation condition are satisfied.
