This second folding roller pair is disposed in opposition to the first folding roller pair, for folding the sheet of paper fed from the feed roller pair in cooperation with the first folding roller pair. A swingable paper guide unit is disposed above the first and second folding roller pairs, for guiding the sheet of paper fed from the feed roller pair selectively to the first folding roller pair or the second folding roller pair. A paper guide plate is disposed between the first and second folding roller pairs, for leading a leading edge of the sheet of paper guided by the paper guide unit to a nip portion of the first folding roller pair or the second folding roller pair. Finally a paper-thrust-posture adjusting unit is provided for adjusting a posture of the leading edge of the sheet of paper when the sheet is forcibly put into the nip portion according to a state of the leading edge of the sheet particularly when the sheet is curled.
