Sheet feeding apparatus and image forming apparatus

An image forming apparatus comprising:

• a stacking member on which sheets are to be stacked;
• a feeding member configured to feed the sheets stacked on the stacking member;
• an image forming unit configured to form an image on a sheet fed by the feeding member:
• and
• a moving device configured to move the stacking member between a first position where the feeding member and the sheets stacked on the stacking member are in contact with each other, and a second position where the feeding member and the sheets stacked on the stacking member are not in contact with each other,
• wherein the stacking member includes a separation unit and an opening portion, wherein the separation unit is disposed at a position facing the feeding member and configured to separate the sheets, and the opening portion is disposed upstream from the separation unit in a sheet feeding direction of feeding by the feeding member,
• wherein the moving device includes a slope portion having a slope along which the sheets are guided toward the separation unit,
• wherein, in a case that the moving device moves from the second position to the first position, the slope portion moves upward, and
• wherein, in a state where the stacking member is at the second position, the slope portion is disposed to protrude via the opening portion to be higher than a stacking surface of the stacking member.
