Abstract PURPOSE:To consecutively separate the sheet different in size one by one and to surely refeed without soiling a formed image, when refeeding for both-face and multiple copying, in an image forming device capable of both-face and multiple copying. CONSTITUTION:A control part controls a pair of carrying rollers 37 so as to accumulate a sheet P on an intermediate tray 24 by a pair of the carrying rollers 37, so that the leading edge of the following sheet S2 longer than the previous sheet S1 obtains the up stream side by a prescribed quantity (d), and the tailing edge of the following sheet S2 shorter than the previous sheet S1 obtains the up stream side than the tailing edge of the previous sheet S1 by the prescribed quantity (d). On the other hand, when the tailing edge of the top sheet S1 is slipped out of a pair of the carrying rollers 37, a pair of carrying rollers 43 refeeds only the top sheet S1 for refeeding. On the other hand, a flapper 45 is provided on the down stream side of a pair of the carrying rollers 43, and the bundle of the sheets S2 and the after is separated/retreated from the top sheet S1, by the flapper 45, to refeed only the top sheet S1.
