Claim:
1. A feed device comprising: a first roller: a second roller provided further to the downstream side in a transport direction of a medium than the first roller; a first motor by which the first roller is driven; a second motor by which the second roller is driven; and a controller that controls the second motor and performs a skew removal operation accompanying reverse transport of the medium by the second roller, wherein the controller causes a suppression current that suppresses the reverse transport speed of the first roller to the reverse transport speed of the second roller or less to flow to the first motor in at least a part of the skew removal operation period in which the skew removal operation is performed by the second roller reverse transporting the medium, the first roller is reversely rotated using a recovery force of the medium that tends to resolve bending formed with the first roller by the second roller reversely transporting the medium in at least a part of the skew removal period in which the skew removal operation is performed by the second roller reversely transporting the medium, and the controller causes a reverse current to flow to the first motor and assists the reversal of the first roller with the recovery force of the medium.
