Image forming apparatus

An image forming apparatus comprising:

• an image forming unit configured to form an image on a recording material;
• a casing accommodating the image forming unit, the casing having a space portion provided at an upper side of the casing and exposing to an outside of the casing;
• a document reading unit disposed above the space portion in a vertical direction, the document reading unit including a document stand configured to support a document and an image reading unit configured to read an image of the document supported on the document stand;
• a sheet discharge unit configured to discharge a recording material on which an image is formed by the image forming unit from an inside of the casing to the space portion;
• a sheet supporting portion disposed at a bottom portion of the space portion and configured to support a recording material discharged by the sheet discharge unit;
• an operation unit disposed above the casing in the vertical direction and downstream of the document reading unit in a sheet discharge direction of a recording material discharged by the sheet discharge unit, the operation unit including a display surface;
• and
• a supporting unit rotatably supporting the operation unit with respect to the casing,
• wherein, if a region which a plurality of the recording material occupies in a case where a maximum number of a maximum size of a recording material supportable on the sheet supporting portion is supported is defined as an occupied region, the operation unit is disposed such that a part of the operation unit in a width direction intersecting with the vertical direction and the sheet discharge direction overlaps the occupied region when viewed in the vertical direction,
• wherein the supporting unit is configured to rotatably support the operation unit between a first position and a second position, the second position being a position where a tilt angle of the display surface with respect to a horizontal direction is larger than a tilt angle in the first position,
• wherein a rotational axis around which the supporting unit rotatably supports the operation unit is positioned downstream of a center of the operation unit in the sheet discharge direction and downstream of the document reading unit in the sheet discharge direction, and
• wherein the supporting unit supports the operation unit such that, in a case where the operation unit is positioned in the second position, a lower end of the operation unit is positioned above the occupied region in the vertical direction.
