An image-forming apparatus equipped with a recirculative document handler, designed in such a manner that when a sensor S2 provided along the document conveyer path is turned on to indicate completion of feeding of a single document, the on/off state of a one-circulation detecting sensor S1, which detects the state of circulating documents, is read in the document-holding section, and the result of addition of "1" to the count of a counter Y which counts fed documents is stored as the maximum document page number when a not-yet-fed document is present in the document-holding section, and thus the one-circulation detecting sensor S1 has not detected one circulation of all the documents, whereas the count of the counter Y is stored as the total document page number when the one-circulation detecting sensor S1 is in the ON state. An additional sheet is fed only when the maximum document page number exceeds the number of fed sheets which have been counted by a counter X.
