An image forming apparatus including: a sheet feeding tray configured to support a sheet; and an apparatus main body configured to support the sheet feeding tray so as to be moveable in a direction parallel with a sheet feeding direction, the apparatus main body including a chute configured to guide the sheet that is fed from the sheet feeding tray, wherein the sheet feeding tray includes a guiding member configured to be displaced between an engaging position at which the guiding member engages with the chute and restrains movement of the sheet feeding tray and a separation position at which the guiding member separates from the chute and permits movement of the sheet feeding tray, and wherein the guiding member is configured to guide the sheet that is fed from the sheet feeding tray toward the chute when the guiding member is located at the engaging position.

A sheet feeder includes a cassette has a sheet container space configured to hold a sheet having a wireless tag. The cassette feeds the sheet to a first side in a first direction. A horizontal direction orthogonal to the first direction is a second direction. A range in the second direction occupied by the wireless tag of the sheet held in the sheet container space is a first range. A range in the second direction including at least a part of the first range is a second range. A range in the second direction occupied by the sheet container space is a third range. In the cassette front wall, a height in a vertical direction in the third range except the second range is smaller than a height in the vertical direction in the second range.
