Abstract: An electrophotographic image forming apparatus includes a driving device including a first gear and a second gear, a power transmitter configured to transfer a rotational force applied in one direction from the motor to the first and second gears; a cam configured to set the power transmitter to one of a release mode in which the motor is disconnected from the first and second gears, a first connection mode in which one of the first and second gears is connected to the motor, and a second connection mode in which the other of the first and second gears is connected to the motor; and a clutch configured to selectively transfer the rotational force applied in the one direction from the motor to the cam.
