A document feeder configured to sequentially feed and eject document sheets so as to insert each document sheet under a stack of already-ejected document sheets. The document feeder includes a feed tray configured to be loaded with the document sheets to be fed, a catch tray configured to be loaded with the document sheets ejected thereon, a feeding mechanism configured to convey the document sheets from the feed tray to the catch tray, a counter configured to count a total number of the document sheets conveyed by the feeding mechanism, and a controller configured to take drive control of the feeding mechanism. The controller is configured to, when the total number counted by the counter exceeds a predetermined value, interrupt driving the feeding mechanism.
