An image forming apparatus includes: a motor; a transfer mechanism configured to transfer driving force of the motor to a load; and a control unit configured to control the motor to rotate a rotor of the motor in a first direction to rotate the load. The transfer mechanism has backlash, and the control unit is further configured to, when control to rotate the rotor in the first direction fails, determine whether or not control to rotate the rotor in the first direction failed due to the motor being faulty, by executing control to rotate the rotor a predetermined amount in a second direction opposite to the first direction.
