    摘要: A sheet feeding apparatus includes a sheet stacking portion for stacking a sheet, a sheet feeding roller for feeding the sheet stacked on said sheet stacking portion, a supporting member, rotatably supported by a base member, for rotatably supporting said sheet feeding roller, and a spring stretched between the base member and an acting portion of the supporting member. The acting portion of the supporting member is located downward with respect to a rotation center of the supporting member when a sheet stacking amount is small, and the acting portion of the supporting member is located upward with respect to a rotation center of the supporting member when a sheet stacking amount is large.
