The folding blade includes a blade portion and a pair of arm portions. The blade portion is selectively disposed in a folding position where the blade portion pushes a folded portion of the sheet into the first nip area and in a retracting position where the blade portion is retracted from the folding position. The pair of arm portions couples both end portions of the blade portion with the pivot shaft. The sheet guide can be passed between the pair of arm portions. Between the blade portion and the sheet guide, a retreating path in which a part of the sheet is retreated when the folded portion is pushed into the first nip area.
