A sheet feeding device including: a sheet-feed roller driven by a drive source; and a spur roller which is opposed to a portion of the sheet-feed roller in an axial direction thereof and which is to be biased toward the sheet-feed roller, the spur roller and the sheet-feed roller cooperating with each other to feed a sheet while holding the sheet therebetween. In the sheet feeding device, the spur roller includes two spurs and an intermediate hub disposed between the two spurs for defining a distance therebetween and having an outside diameter smaller than that of each of the two spurs. Further, the sheet-feed roller includes: a large-diameter portion opposed to the intermediate hub so as to be interposable between respective radially outer portions of the two spurs; and two small-diameter portions which are respectively located on axially opposite sides of the large-diameter portion so as to extend beyond respective outer axial end faces of the two spurs and each of which has an outside diameter smaller than that of the large-diameter portion.
