An image is recorded on a recording material line by line during transport of the recording material by a drive roller and a driven roller. Rotation of a motor is transmitted to the drive roller via a traction drive decelerating mechanism. An output shaft of the traction drive decelerating mechanism and a first end of the drive roller are connected on the common axis with a connector. A second end of the drive roller and the traction drive decelerating mechanism are cantilever-supported by a drive roller supporting mechanism.
