ajl11. The front side is exposed and scanned by the optical system 5b to form a latent image on the photoreceptor drum lb, and a back side copy is formed on the back side of the front side copied transfer paper 78 according to the development, transfer and fixing process. The original 15a and the transfer paper 7a on which both sides have been copied are placed in a paper output tray 60.
．． 55 etc. (it is reversed or the sorter 56 is selected as necessary) 6.Next, it is also in the double-sided original-double-sided copy mode, but a predetermined number of sheets set to repeat from one double-sided original are ejected. Consider when in repeat duplex copy mode to obtain a duplex copy. Basically, it is the same as in the 1-1 double-sided copy mode described above, but the switching claw 29 switches to the transfer paper reversing intermediate tray 23 instead of the transfer paper reversing conveyance device 23.
4 is selected. First, the document 15 is fed onto the contact glass 4a by the automatic document feeder 13a.
For each photoreceptor drum Ia, the copying operation is repeated for the number of repeat sheets, and front side: ] copies are created. The transfer paper 7a on which the front side has been copied is sequentially discharged to the transfer paper reversing intermediate tray 24 and temporarily stored therein. When the front side copying for the number of repeat sheets is completed, the original 15a on the contact glass 4a'' is conveyed and set on the contact glass 4b while being reversed by the original reversing device 35. On the other hand, a means for detecting the number of ejected sheets is provided in the transfer paper reversing intermediate tray 24 or in the conveyance path just before the transfer paper reversing intermediate tray 24.
When storage of the paper a is detected, the partition pressure plate 27 is switched to the paper feed roller 28 side, and the paper is in a standby state to be fed to the photosensitive drum 1h side. As a result, the back side of the original 15a set on the contact glass 4b is copied on the photosensitive drum lb side, and the transfer paper 7a on which the front side has been copied is transferred from the intermediate tray 24 by the paper feed roller 28 in an inverted state. The sheets are fed one by one and one duplex copy is completed.

In this case as well, there is a 1-1 double-sided copy mode and a repeat double-sided copy mode, but in the former case, the transfer paper reversing conveyance device 23 is selected, and in the latter case, the transfer paper reversing intermediate tray 24 is selected. . on the other hand,
On the manuscript side, two methods can be adopted. First, all the originals are placed on the original table 1.4a of the automatic document feeder 13a, and after the front side copy of the odd-numbered (front side) i original 15a is completed on the photoreceptor drum la side, the contact glass The odd-numbered document 15a on 4a is immediately ejected through the document transport path 21-contact 1-glass 4b, while the next even-numbered document 15a on the document table +4a is passed through the contact glass 4a-document transport. There is a method in which the paper is passed through the channel 21 and conveyed and set on the contact glass 4b for back side copying. That is, the document reversing device 35 becomes inactive. Also, the originals are divided into those for the front side and those for the back side, and the one for the front side is set as the original 15a on the document table 14b, and the one for the back side is set as the original 15b on the document table 14b, and each automatic document transport is performed. Device 13a
, 13b may be operated separately. At this time, the document conveyance path 21 is closed and the document 15a subjected to front-side copying is delivered to the paper discharge tray 39.

Since the transfer paper is conveyed from the photoreceptor drum 1a side to the photoreceptor drum Ib side by the substantially straight and short transfer paper conveyance path 20, the probability of occurrence of a transfer paper jam is reduced and the copying speed is also improved. This also applies to the document side, and since the document transport path 21 connecting the automatic document transport stations 13a and +3b is substantially straight and short, document jams are reduced. Also, transfer paper 7a
After the surface copy, the transfer paper is reversed by the transfer paper reversing device 23 and conveyed to the photoreceptor drum 1b side, so that the photoreceptor drum 1
This is the same as when the paper is fed toward the optical system 5a,
The arrangement of the copying process components such as 5b can be made exactly the same on both the photosensitive drums 1a and 1b.

得られるものである。Although this double-sided copying machine can also select a single-sided copy mode and perform various single-sided copy processes, the single-sided composite copy mode will be explained here. That is, for example, as shown in FIG. 2, there is a case where it is desired to make a composite copy of two sheets of 85 size original 15 onto 84 size transfer paper 7. In this case, the original 15a indicated by A
is set on the automatic document feeder 13a, and document 1 indicated by B is placed on the automatic document feeder 13a.
5h on the automatic document feeder 13b and start copying. First, an image of the original 15a is formed on the photosensitive drum 1a, and this image is transferred to the left half of the transfer paper 7a. Then, this transfer paper 7a is fed into the transfer paper conveyance path 20 and directed toward the photosensitive drum lb side. At this time, the transfer paper reversing device 22, particularly the transfer paper reversing and conveying device 23, is in a non-operating state, and the transfer paper 7a is sent in a non-reversing state. Therefore,
An image is formed based on the original 15b on the rear image forming means +8b side and transferred to the transfer paper 7a. The image 15b is transferred to the right half of the transfer paper 7a. In this way, a single-sided composite copy can be easily obtained.

In this case, a double-sided document is set in the automatic document feeder N13a, and first, the front side (corresponding to the A document) is copied on the photosensitive drum 1a side and transferred to the left half of the transfer paper 7a. Then, the document is reversed by the document reversing device 35 and sent to the automatic document feeder 13) 1 side, and the back side of the document (corresponding to the B document) is copied on the photosensitive drum lb side, and the right half of the transfer paper 7a is This results in a single-sided composite copy with the front and back sides of the double-sided original spread out. Note that if the size of the transfer paper to be used is large, the manual paper feed section 7o may be used.
