ABSTRACT:
The present invention provides a recording apparatus comprising convey means for conveying a sheet in a predetermined convey direction, a pair of rollers arranged downstream of the coney means in the convey direction for conveying the sheet in the convey direction or in a reverse direction by rotation in a forward direction or in a reverse direction, and control means for controlling the convey means and the pair of rollers. The control means controls these elements in such a manner that, after a sheet conveyed by the convey means is conveyed in the convey direction by a predetermined amount by the pair of rollers, the pair of rollers are rotated in the reverse direction while applying a conveying force in the convey direction to the sheet using the convey means, thereby conveying the sheet in the reverse direction until the sheet passes through a nip formed between the pair of rollers.
