Abstract
A sheet folding apparatus includes: a folded part forming unit that forms a folded part on the sheet by nipping a curved portion formed on a part of the sheet between an upstream first sheet conveying unit and a downstream second sheet conveying unit by holding a part of the sheet by the first sheet conveying unit and applying conveying force to the sheet to reverse the sheet upstream by the second sheet conveying unit; and a sheet leading end detection unit disposed downstream of or at almost same position as the second sheet conveying unit. The sheet is conveyed based on a detection timing of the sheet leading end detection unit such that the leading end of the sheet protrudes by a predetermined protrusion amount from the second sheet conveying unit immediately before applying conveying force to the sheet to reverse the sheet.
