Abstract
An image forming apparatus includes a motor, a first coupling, an attachable/detachable unit, a detector, a phase determiner, and a controller. The motor rotates a rotary member through the first coupling and the attachable/detachable unit. The controller includes a first control mode and includes a second control mode. In the second control mode, in a case where a rotor load torque applied value is greater than a first predetermined value and a rotor rotational speed value is greater than a second predetermined value, the controller switches from the second control mode to the first control mode.
