摘要： An automatic sheet feeder for an image forming apparatus includes a tray to be loaded with a stack of sheets, a side guide for preventing the sheets from skewing, and a sheet feeding mechanism for sequentially picking up and feeding the sheets, the top sheet being first. The tray includes an abutment parallel to a direction of sheet conveyance. The stack of sheets abut against the abutment at one side thereof. The side guide is movable toward and away from the abutment in matching relation to the size of the sheets. The sheet feeding mechanism is positioned at the intermediate between the abutment and the position of the side guide matching with sheets of minimum size available with the sheet feeder.
