A sheet processing apparatus that forms a folding line on a sheet includes first and second folding rollers that form a folding line on the sheet by rotating a bent sheet while pinching from sheet surfaces and a first pressing unit that presses the second folding roller against the first folding roller in an arbitrary portion in a rotating shaft direction of the second folding roller.

Sheet processing apparatus and image forming system for forming a folding line on a sheet

A sheet medium adjustment apparatus, e.g., in an image forming system, includes: an ejector to eject a conveyed sheet; a stacking device to stack each sheet ejected from the sheet ejector into a stack on a tray; a moving device to shift the stacking device in a movement direction perpendicular to a sheet-ejecting direction; a sheet aligning member to align ends of the sheets in the stack that are parallel to the sheet-ejecting direction; a stepping motor to move the sheet aligning member; and an evacuation device to evacuate the aligning member by an amount representing an evacuation displacement in the movement direction at a timing of aligning the sheet, the evacuation displacement being determined adaptively according to at least one of an attribute of a given sheet in the stack, an attribute of the stack as a whole and an attribute of the tray.
