PROBLEM TO BE SOLVED: To secure a high print speed by keeping sheets at equal intervals even in case of retarded separation method. SOLUTION: A plurality of sheets S are fed by a pickup roller 11, and if a second or following sheet S is detected by light transmission type sensors 23, 24 when the rear end of each sheet S separately fed by cooperation of a feed roller 12 with a retard roller 13 passes through the nip portions of the feed roller 12 and the retard roller 13, the timing to start the feed of the next sheet S by the pickup roller 11 is retarded by a control part.
