After this latent image is developed by the developing device Ga, it is transferred from the paper feed section 8a side to the transfer paper 7a at a predetermined timing by the action of the transfer roller V-jar 9rl. Then, after passing through the device 12.1, the surface copying onto the transfer paper 7a is completed. The copying operation for the original 15a is repeated for the number of repeat sheets on the photosensitive drum 1a side to create a front side copy.The transfer paper 7a on which the front side has been copied is sequentially transferred to the transfer paper reversing intermediate tray 2.
4 and is temporarily stored. At this time, in the transfer paper reversal intermediate tray 24, the partition plate 27 is in the initial state as shown in FIG. stored inside. When the front side copying for the number of repeat sheets is completed, the originals 15a on the contacts 1 to 4a are conveyed and set on the contact glass 4b while being turned over by the original reversing device 35. On the other hand, the transfer paper reversing intermediate tray 24
The middle paper is equipped with a paper discharge number detection means in the conveyance path just before that, and when it is detected that the transfer paper 7a corresponding to the number of repeat sheets has been stored, the partition plate 27 moves to the 38 paper rollers as shown in FIG. 28 side, pressurizes the already stored transfer paper 7a against the paper feed roller 28, and enters a standby state for paper re-feeding to the photosensitive drum Ib side. Therefore, this transfer paper 7a is transferred to the paper feed section 7.
2, and a storage section 73 is secured on the right side of the partition plate 27. However, contact glass 41

Back side copying will be performed on the b side, and the transfer paper 7a on which the front side has been copied is transferred from the intermediate tray 24 to the paper feed roller 28.
The paper is fed one by one in a reversed state, and double-sided copying is completed. At this time, if you press the front side, the next IJITQ l'',)a has already been printed on the contact glass 4a, and the photosensitive drum Jd side will print the predetermined number of copies for each original 1;5a. The front side copy is performed, and the transfer paper 7a whose front side has been copied is sequentially stored in the storage section 1:3 of the transfer paper reversal intermediate tray 24.In other words, on the later side, it is The back side copy for the front side copy will be 1?ZJ/WJ, and at the same time, the next front side copy will be TI on the previous stage side.

Next, let us consider the 1-1 duplex copy mode, which is also in the double-sided original-to-duplex copy mode, but in which a double-sided copy is made from one double-sided original. Basically, it is the same as in the repeat double-sided copy mode described above, but the switching claw 29 is switched and the transfer paper reversing conveyance device 23 is selected instead of the transfer paper reversing intermediate tray 24. At this time, the document 1.5a is set on the document table 14a. When copying is started, the original 15a is fed, conveyed by the conveyor belt 16a onto the contact lens 1-glass 4a, and stopped. Therefore,
The optical system 5a exposes and scans the surface of the document 15a on the contactor 1-glass 4a and rotates the photoreceptor 1-ram I.
A latent image is formed on a. After this latent image is developed by the developing device 6a, it is transferred to the transfer paper 7a fed at a predetermined timing from the paper feed section 8a side by the action of the separation transfer charger 9a.
