A sheet feeding apparatus includes a sheet stacking portion on which a sheet is stacked, and a one-way clutch configured such that (i) in delivering the sheet stacked on the sheet stacking portion toward a separation nip, rotation of a drive shaft in a first rotational direction is transmitted through the one-way clutch, a drive gear and a gear train rotate a pick-up roller without slipping of the one-way clutch, and (ii) after a leading edge of the sheet has reached the separation nip, the pick-up roller is dragged and rotated by the sheet conveyed by a feed roller, rotation of the pick-up roller is transmitted through the gear train to the drive gear, and the drive gear is rotated in the first rotational direction with respect to the drive shaft that is rotated in the first rotational direction while the one-way clutch is slipping.
