Abstract

A sheet feeding apparatus includes a sheet supporting portion including a supporting surface, an abutment portion against which a leading edge of the sheet abuts, a feeding rotator configured to feed the sheet, and a first friction member provided on the supporting surface so as to face the feeding rotator. The first friction member includes a first friction surface having a static friction coefficient greater than that of the supporting surface, a trailing end supporting portion configured to support a trailing end portion of the sheet curved upward, and a second friction member disposed upstream of the first friction member in the sheet feeding direction on the supporting surface. The second friction member includes a second friction surface which has a static friction coefficient greater than that of the supporting surface and is configured to be in contact with the sheet supported by the supporting surface.
