PURPOSE: A stack roller with a flange integration stack sheet is provided to increase production efficiency and reduce a manufacturing cost without an extra flange. CONSTITUTION: One or more second rollers(330) rotate to have a fixed phase difference with first rollers(320). A plurality of second stack sheets is formed on a part of an outer circumference surface of the second rollers. Thickness of lower sides of first stack sheets and the second stack sheets connected to the first rollers and the second rollers is thicker than the thickness of upper sides of the first stack sheets and the second stack sheets. The first stack sheets and the second stack sheets lift both ends of a medium transferred on a carrying way to a top through the lower sides of the first stack sheets and the second stack sheets.
