Abstract: A second driven roller that is rotated by following a second driving roller has a larger outer diameter than a first driven roller. A front edge of a recording sheet being lifted up from a first nip contacts the second driven roller, and hence the front edge does not directly hit the first driven roller. The second driven roller rotates at a higher rotational speed than a rotational speed of the first driven roller. The second driven roller gently flips the front edge of the recording sheet which has contacted the second driven roller, and leads the front edge quickly to the first nip. The front edge of the recording sheet is smoothly led to the nip.
