A sheet feeder, which is included in an image forming apparatus, includes a sheet tray on which a recording medium is loaded, a regulating member, a link mechanism, and a guide storage. The regulating member is movably disposed to regulate a position of the recording medium loaded on the sheet tray and has guide portions having a height higher than a maximum possible thickness of a sheet stack loadable on the sheet tray and the height thereof is changeable. The link mechanism rotatably supports the sheet tray with respect to a tray storing position and a sheet feeding position. The guide storage stores the guide portions of the regulating member as the link mechanism moves the sheet tray from the sheet feeding position to the tray storing position and has a depth set to be greater than a length in a height direction of the guide portions. |
