A sheet conveyer device to convey a sheet in a conveyer path, including a first roller pair arranged in an intermediate position in the conveyer path, a feeder to feed the sheet toward the first roller pair during a feeding operation, a discharge portion, on which the sheet is discharged, a second roller pair arranged in the conveyer path in a position closer to the discharge portion than the first roller pair, a control unit to control the first and the second roller pairs to rotate synchronously, and a judging system to judge whether a sheet feeding error has occurred in the feeder, is provided. The control unit controls the first and the second roller pairs to rotate synchronously in a second direction during the feeding operation and in a first direction when the judging system judges that the sheet feeding error has occurred during the feeding operation.
