Sheet feeding apparatus to be connected to image forming apparatus

A sheet feeding apparatus configured to be connected to an image forming apparatus and to feed a recording medium to the image forming apparatus, the sheet feeding apparatus comprising:

• a housing part that includes
• a first frame,
• a second frame,
• a feed unit that is positioned between the first frame and the second frame in a rotational axis direction of the feed unit and is configured to feed the recording medium,
• a first member fixed to the first frame and to the second frame, and
• a weight unit fixed to the first member;
• and
• a supporting member that has a supporting surface configured to support the recording medium and is movable in a first direction from a first position to a second position, the first position being a position at which the feed unit is able to feed the recording medium, the second position being a position at which the recording medium is able to be stacked in the supporting member,
• wherein the housing part includes a housing upstream end that is an upstream end of the housing part in the first direction,
• wherein the housing part includes a housing downstream end that is a downstream end of the housing part in the first direction,
• wherein when the supporting member is at the first position, the supporting surface of the supporting member is positioned, in the first direction, between the housing upstream end and the housing downstream end,
• wherein the housing part is a part of the sheet feeding apparatus excluding the supporting member,
• wherein the housing part includes an upstream portion that is a portion positioned upstream in the first direction from a center of gravity of the housing part,
• wherein a first standard-sized sheet is a largest standard-sized sheet that can be stacked on the supporting surface,
• wherein a first maximum number of sheets is a maximum number of the first standard-sized sheets that can be stacked in the supporting member, and
• wherein weight of the upstream portion is greater than weight of the maximum number of the first standard-sized sheets.
