Abstract
An image forming apparatus includes a spool that holds a roll of print medium; an image forming device that forms an image on the medium; a transporting device including a transport rotary member that transports the medium to the image forming device, and a drive source that generates drive force; and a drive force transmission device which transmits the drive force to the spool when the transport rotary member rotates in a medium rewinding direction, and which includes a first gear train for rotating the spool in the same direction as the transport rotary member when the transport rotary member and the spool rotate in the same direction during the transport of the medium and a second gear train for rotating the spool in an opposite direction to the transport rotary member when the transport rotary member and the spool rotate in opposite directions during the medium transport.
