A sheet feeding device includes a feeding roller that is driven to rotate, and a base plate to stack sheets thereupon. The sheet feeding device is configured to rotate around a supporting axis thereof in directions to contact and separate from the feeding roller. A base plate pressing member is configured to press the base plate toward the feeding roller, such that an uppermost sheet of the stack of sheets stacked on the base plate contacts the feeding roller in order to be fed by the feeding roller. A first friction device is arranged in a vicinity of a first part of an upper surface of the base plate so as to oppose the feeding roller. The first friction device is configured to provide a bottom sheet of the stack of sheets stacked on the base plate with a first frictional resistance greater than a predetermined value. A second friction device is arranged upstream of the first friction device in a sheet feeding direction and is configured to provide the bottom sheet of the stack of sheets stacked on the base plate with a second frictional resistance greater than the predetermined value.
