Abstract: A toner cartridge includes a toner cartridge main body having a cylindrical toner container that contains toner therein, a toner discharge port disposed on one end of the toner container, and a rotating shaft disposed on the other end of the toner container; and an annular IC chip holder that is fitted to the rotating shaft of the toner cartridge main body to rotate together with the toner cartridge main body, and has a notch formed in an outer peripheral surface in which an IC chip is mounted, wherein the IC chip holder rotates together with the toner cartridge main body until the IC chip holder is fixed to an IC chip contact holder having a contact member for contacting a terminal of the IC chip disposed in the image forming apparatus main body.

Abstract: There is provided a technique which can realize stable loading performance irrespective of the state of a loaded object loaded on a tray. A loading information acquisition unit 106 acquires loading information relating to a sheet loading height on a loading tray 101 on which a sheet subjected to a specified processing is loaded, and a press force adjusting unit 107 moves, based on the loading information, at least one of the loading tray 101 and a pressing unit 104 to press from above the sheet loaded on the loading tray in a direction in which the loading tray and the pressing unit 104 are distanced from each other.

Abstract: A sheet alignment apparatus includes a feeding section, stopper, stacking tray, support portion, and first and second press portions. The first press portion presses the portion in the vicinity of the downstream side edge of a sheet bundle composed of the sheets that have been stacked on the stacking tray to a level higher than a first predetermined height against the support portion. The second press portion presses the portion in the vicinity of the downstream side edge of a sheet bundle composed of the sheets that have been stacked on the stacking tray to a level higher than a second predetermined height that is higher than the first predetermined height against the support portion.
