    摘要: A sheet processing apparatus includes a processing tray on which sheets are stacked in a bundle form, an intermediate portion stapler which staples the intermediate portion of the sheet bundle stacked on the processing tray, a sheet bundle conveying member which conveys the stapled sheet bundle, a curved sheet bundle conveying path which is downwardly curved on the downstream side of the processing tray with respect to the sheet conveying direction and adapted to guide the sheet bundle conveyed by the sheet bundle conveying member, and a folding device which is arranged in the intermediate portion of the curved sheet bundle conveying path and which folds the stapled sheet bundle, wherein the processing tray is set to be lower on the upstream side than on the downstream side with respect to the sheet conveying direction, and wherein the curved guide path has an extended portion extending to a position under the stacking portion.

    摘要: A folded back portion flattening device includes a gripper and a presser. The gripper grips a sheet bundle formed into a booklet with the folded back portion protruding from the gripper. The presser presses the folded back portion of the sheet bundle gripped by the gripper, and includes pressing rollers which have pressing rotational surfaces and which are disposed along the folded back portion. The pressing rotational surfaces press the folded back portion. The pressing rollers are disposed so that the rotational pressing surface of a second pressing roller, which presses the folded back portion after the rotational pressing surface of a first pressing roller has pressed the folded back portion, presses deeper into an edge of the sheet bundle than the rotational pressing surface of the first pressing roller. At least one of the gripper and presser is movable in a direction parallel to the folded back portion.
