A sheet feeding apparatus includes a sheet stacking portion for stacking thereon a sheet, a sheet feeding portion for axially supporting a sheet feeding roller, and a spring portion actable on the sheet feeding portion. The spring portion acts on the sheet feeding portion so that the sheet feeding roller is pressed against the sheet with a pressing force when a sheet stacking amount is large and so that the pressing force is decreased by canceling moment created by a weight of the sheet feeding portion when the sheet stacking amount is small.
