An image forming apparatus (1) comprising, an original reading means for reading an image of an original, an image forming means for forming the image read by the original reading means on a sheet, a sheet conveying means (17,18) for conveying the sheet to the image forming means, a re-supplying means (27) for directing the sheet on which the first image was formed by the image forming means to the image forming means again by re-circulation of the sheet to form a second image on the sheet, and a timing control means for changing the timing for the formation of the first image and the timing for the formation of the second image to form the first and second images on the single sheet side by side.

Signature printing with an automatic duplexing copier (10) by simultaneously presenting plural document sheets (F1, F2, etc.) to the imaging station (23) of the copier in a predetermined nonserial page order for producing a set of signature copy sheets (S1, S2, etc.) suitable for subsequent center-folding into signature sets. A normal serial set of document sheets is loaded into an automatic document re-ordering and presenting system (20) (associated with the copier) which automatically reorders that set of document sheets into a predetermined nonserial reordered page order for signature pair page order "two-up" copying. The pairs of automatically reordered document sheets are preserted automatically to the imaging station of the copier to be copied in the reordered page order to provide collated page order signature sets automatically with the copier for on-line center-folding and finishing without requiring any manual reordering of either the document sheets or the signature copy sheets. The automatic re-ordering includes automatic 180° rotation of alternate pairs of simplex document sheets to provide proper orientation of the document pages for the automatic duplex copier. The document sheets are either automatically separated into two stacks for two document sheets to be presented simultaneously lengthwise (short-edge-first) in parallel to one side of the imaging station (see Fig. 3a), or reordered into one stack for sideways (long-edge-first) presentation from an orthogonal direction (see Fig. 3b).

A copier is arranged to produce a developed image of an original on one half of an imaging area of an imaging element and to transfer this image to one half of a copy sheet. To produce a booklet from a number of originals (303), half of the originals are fed to an exposure platen but only odd numbered ones are scanned to produce copies on one half of one side of copy sheets (301 and 302). The copy sheets are then reversed and reloaded in reverse order and the remaining originals are similarly fed and scanned. The originals are then restacked in the reverse of their original order and the process is repeated to produce copies on the halves of the copy sheets which are still blank.
