Abstract
The image forming apparatus includes a motor including at least three coils, first terminals of which are connected to one another; and a motor control unit. The motor control unit detects a stopping position of the motor by executing measuring processing including performing control so that a coil current flows from a first coil to a second coil and measuring a current value. The motor control unit is configured to perform control so that the coil current flows from the first coil toward the second coil in a first period, attenuates the coil current in a second period, and perform control so that a portion of the coil current flows from a second terminal of the second coil, via a second terminal of a third coil, to the third coil in a third period within the second period.
