Abstract
To avoid displacement of the fold formed on a sheet and misalignment between sheets when a fold is formed on a bundle of sheets stacked one on top of another, a sheet folding apparatus, for forming a plurality of folds on the sheet on which an image is formed, includes a first folding section and a second folding section. The first folding section has a first folding roller, a second folding roller in contact with the first roller, and a first folding plate member for inserting the first fold of the sheet between the first and second folding rollers. The second folding section has the second folding roller, a third folding roller in contact with the second folding roller provided downstream from the first folding roller in the sheet feeding direction, and a second folding plate member for inserting the second fold of the sheet between the second and third folding rollers. After the first fold has been formed on the sheet in the first folding section, the second fold of the sheet is formed in the second folding section.
