ABSTRACT:
An image forming apparatus includes an endless belt that is rotated, an image forming device configured to form an image on a recording medium which fed on the endless belt, a cleaning roller configured to be rotated and clean the endless belt, a pair of registration rollers configured to be rotated in a recording medium feeding direction and to feed a recording medium to the image forming device, and a motor configured to rotate in two directions. The image forming apparatus may further include first, second, and third gear mechanisms. The first and second gear mechanisms are configured to switch between transmission and non-transmission of a driving force to the cleaning roller according to rotational direction of the motor. The third gear mechanism is configured to switch between transmission and non-transmission of the driving force to the registration roller according to the rotational direction of the motor.
