A recorded medium feeding device includes a pickup roller that feeds recorded medium downstream from a setting position by contacting with the recorded medium and rotating and a separating means for separating recorded medium to be fed and subsequent recorded media from the next page onward. The positions of a nip point of the separating means and a place where the pickup roller contacts the recorded medium in the direction orthogonal to the recorded medium feeding direction with respect to a recorded medium of a predetermined size to be fed by the pickup roller are located within a range deviated to one side from the center of the recorded medium of the predetermined size. A path elongating portion that elongates the feed path length of the recorded medium by abutting the recorded medium is apart from the nip point and the place where the pickup roller contacts the recorded medium.
