To reduce possibilities of damages and wrinkles on a medium when the medium is folded at a folding position by a folding roller pair.SOLUTION: A medium folding device 50 comprises: a stack part 52 on which a medium conveyed from an introduction passage 51 is placed; a folding roller pair 53 which, after the medium is stacked on the stack part 52, folds the medium at a folding position C; and a deflection forming mechanism 60 which includes a first contact part 61 which can be in contact with a front end E1 in a conveyance direction +R of the medium stacked on the stack part, and a second contact part 62 which can be in contact with a rear end E2 in the conveyance direction +R of the medium stacked on the stack part 52, and deflects the medium toward the folding roller pair 53 by shortening a relative distance between the first contact part 61 and the second contact part 62 to make the folding roller pair 53 nip the folding position C of the medium.SELECTED DRAWING: Figure 2 【課題】媒体の折り位置を折りローラー対で折る際に、媒体に傷が付いたり皺ができたりする虞を低減する。【解決手段】媒体折り装置５０は、導入経路５１から搬送される媒体を載置するスタック部５２と、スタック部５２に媒体がスタックされた後、媒体を折り位置Ｃで折る折りローラー対５３と、スタック部にスタックされた媒体の搬送方向＋Ｒの先端Ｅ１に当接可能な第１当接部６１と、スタック部５２にスタックされた媒体の搬送方向＋Ｒの後端Ｅ２に当接可能な第２当接部６２とを有し、第１当接部６１と第２当接部６２との相対距離を短くして媒体を折りローラー対５３に向けて撓ませることにより、媒体の折り位置Ｃを折りローラー対５３にニップさせる撓み形成機構６０と、を備える。【選択図】図２
