  • a rotating body that forms the image;

    a motor that rotationally drives the rotating body;

    a current measurer that measures a motor current flowing through a current supply path including a winding of the motor at a measurement timing that is a timing after the motor is started;

    a torque acquisitor that acquires a torque value of the motor, based on a measured value of the motor current; and

    a corrector that performs correction to cancel a current change amount based on a characteristic change depending on a temperature state of the motor at the measurement timing, in acquisition of the torque value by the torque acquisitor.
