A sheet feeding device that feeds sheets by a sheet feeding unit from a sheet feeding cassette storing the sheets, in which positions of rotation centers of a lifting plate and a lifting plate pressing member are varied from each other in such a manner that a rotation track of an edge of an opening of the lifting plate pressing member and a rotation track of a vertical surface of an engaging member provided on the lifting plate intersect with each other, so that the edge is engaged with the vertical surface at the intersection position of the rotation tracks to restrict rotation of the lifting plate when the lifting plate moves upward before a lifting operation of the lifting plate pressing member.
