摘要： A sheet feeding apparatus includes a stacking surface on which a sheet is stacked, a feed portion configured to feed the sheet in a sheet feeding direction, and first and second detecting portions disposed at positions different from each other in a width direction orthogonal to the sheet feeding direction and so as to overlap with the stacking surface in a view from a height direction orthogonal to the stacking surface. The first and second detecting portions detect height positions which are positions in the height direction of an uppermost sheet. In addition, a control portion stops feeding the sheet by the feed portion based on at least one a height position detected by the first detecting portion and a height position detected by the second portion in feeding the sheet.
