A sheet folding device includes: a conveying path to convey a sheet; a conveying unit to convey the sheet to downstream in a sheet conveying direction; a folding-conveying path branching from the conveying path downstream of the conveying unit in the sheet conveying direction to discharge a folded sheet; a pair of folding rollers arranged in a branching portion of the folding-conveying path to fold the sheet in a nip formed between the rollers; a leading end stopper on which a leading end of the sheet is abutted to determine a folding position; an angle adjustment unit that adjusts an angle of the leading end stopper; a folding-length measurement unit to measure lengths of both edges of the sheet; and a control unit that operates the angle adjustment unit based on the measurement result of the folding-length measurement unit to variably control the angle of the leading end stopper. |
