PROBLEM TO BE SOLVED: To provide a sheet processor capable of suppressing generation of wrinkles around a fold when folding a sheet. SOLUTION: The sheet processor to fold a sheet by forming a curved portion of the sheet and pushing the curved portion into a pair of rollers has a pushing member to press the sheet into the pair of rollers. The pushing member has a push-support member to support the push of the curved portion into the pair of rollers by the pushing member by pushing an area adjacent to the curved portion to the pair of rollers, and is movable between the evacuation position separate from the sheet and the operational position to push the curved portion of the sheet.
