PROBLEM TO BE SOLVED: To provide a paper center folding device for folding a bundle of paper capable of accurately pushing the folding position of the bundle of paper folded by sandwiching a folding plate for pushing the bundle of paper between a pair of folding rollers. SOLUTION: Two fixed rollers 128 are fixed to a device frame 134 in position and a movable roller 130 energized toward the fixed rollers 128 are slidably mounted on the device frame 134, thereby slidably sandwiching a bundle of paper pressing member 100 between the fixed rollers 128 and the movable roller 130. When a bundle of paper A is pressed into the nip portion of the pair of rollers 88, the movable roller 130 is moved, following changes in the nip portion of the pair of folding rollers 88 to accurately move the folding plate 89 in the folding position of the bundle of paper A.
