Abstract
A separation roller for a sheet feeding apparatus includes an outer circumferential portion formed from an elastic material, a core portion to which the outer circumferential portion is attached; and a flange portion including a plurality of projecting portions each projecting to an outside in a radial direction with respect to the core portion. At least one of the plurality of projecting portions includes a first surface provided on a side portion thereof on an upstream side in a first direction in which the separation roller rotates in such a manner as to follow the rotary feeding member rotating to feed the sheet. The first surface extends more upstream in the first direction at a position further on an outside in a radial direction with respect to a rotation axis of the separation roller as viewed in the axial direction.
