The present invention relates to a sheet feed device comprising a door for supporting one of the rollers of a feed roller pair for feeding a sheet, mounted on the apparatus main body so as to be opened or closed on the one end part side in the roller pair axis direction such that the one roller is pressured against the other roller of the feed roller pair provided in the apparatus main body at the time the door is closed, comprising: an outer door supported rotatably on the apparatus main body on the one side end part side in the feed roller pair axis direction; an inner door for supporting one of the rollers of the feed roller pair, supported rotatably with respect to the outer door on the one side end part side in the one roller axis direction. The one roller of the feed roller pair is separated with respect to the other roller at the time of opening the outer door, and thereafter the inner door is rotated while maintaining the angle with respect to the outer door according to the rotation of the outer door.
