Abstract: An input apparatus, that displays an editing screen including a keyboard on a display unit, includes a display control unit and a determination unit. The display control unit is configured to cause the display unit to display an input screen including at least an input item in which data is input via the keyboard thereon. The determination unit is configured to determine, based on the input item, that is a target in which data is input via the keyboard, whether a key for accepting an instruction to change the input item, that is a target in which data is input via the keyboard, to a next input item is to be displayed together with the keyboard on the display unit.

Abstract: An image forming apparatus forming an image on a recording material includes a main assembly and a supporting member for supporting a plurality of cartridges. The supporting member is movable to an outside position, a first inside position where the cartridges are positioned inside of the main assembly, and a second inside position where the supporting member is movable to the outside position and the first inside position. A first positioning portion positions an associated cartridge when the supporting member is located at the first inside position, and a first preventing portion prevents rotation of the associated cartridge about the first positioning portion. In addition, a second positioning portion positions the associated cartridge when the supporting member is located at the second inside position, and the second positioning portion is spaced from the associated cartridge when the supporting member is located at the first inside position.
