Abstract
A sheet pressing device of the present invention includes: a pair of pressing rollers 70 that press, in a fold thickness direction, a fold of a folded sheet bundle BS conveyed in a folded state; and a pressing roller unit 56 that moves the pressing roller pair in a sheet fold direction while supporting the same. The pressing roller pair 70 presses the fold in one of a first region R1 where rollers of the pressing roller pair 70 are brought into pressure contact with each other and a second region R2 adjacent to the first region R1 on an upstream side thereof where rollers of the pressing roller pair 70 are opposed to each other at an interval. With this configuration, it is possible to minimize damage on a sheet end portion and reduce a moving load of the pressing roller pair 70.
