PURPOSE: A sheet feeding apparatus and an image reading apparatus are provided to exactly detect whether the sheet is placed at the exact position or not. CONSTITUTION: An original document tray(101) includes a placing plate(1) on which the sheets are placed and which can be lifted and lowered and to move the sheets to a position at which the sheets can be fed by a pickup roller(51), a detection unit which detects that sheets are placed on the placing plate(1), and a curl suppressing member(7) which presses a central portion in a width direction perpendicular to the sheet feeding direction of the accommodated sheets to suppress upward curl of downstream edges in the sheet feeding direction of the sheets.
