Abstract: Disclosed is an image forming apparatus. The image forming apparatus includes a body frame, a support roller placed at one side of a movement path of a printing medium, a transfer roller assembly placed at the other side of the movement path of the printing medium at a position adjacent to the support roller, and a door to open or close the body frame so as to expose the movement path of the printing medium. The transfer roller assembly has a rotating axis kept at a fixed position of the body frame, and is moved away from the support roller in linkage with an opening operation of the door.
