Claim:
A sheet feeding device for feeding a sheet to an image forming section, the device comprising: a sheet feeding roller which feeds sheets one-by-one; a sheet stacking section in which a plurality of sheets can be stacked, and which pushes a sheet against the sheet feeding roller; an upper guide member able to move between a guiding position at which, at a time of double-sided printing, the upper guide member re-feeds to the image forming section an inverted sheet which is sent-in by a sheet re-feeding section, and a withdrawn position, at which sheet feeding of the sheet stacking section is possible; and a lower guide member which is rotatable and which abuts leading ends of sheets stacked in the sheet stacking section, wherein a guide path, which guides a sheet which is re-fed at the time of double-sided printing, is formed by the upper guide member and the lower guide member rotating interlockingly via a linking member disposed on the upper guide member, wherein the rotation of the lower guide member induces rotation in the upper guide member.
