Abstract
A sheet feeding device includes a cassette storage part, a sheet feed cassette, a pickup roller, a feed roller, a retard roller, a retaining member, and a pushing mechanism. The pushing mechanism pushes the retaining member so that the retard roller is pushed to contact with the feed roller. The pushing mechanism includes a pushing member that contacts and pushes the retaining member, and a biasing member that biases the pushing member. In a plane perpendicular to a rotation shaft of the retard roller, a pushing direction of the pushing member in a push contact position against the retaining member forms an angle of 45 degrees or less, with a straight line connecting the center of the rotation shaft of the retard roller and the center of a rotation shaft of the feed roller.
