IMAGE FORMATION DEVICE

PROBLEM TO BE SOLVED: To realize to continuously carry out reversal and conveying of a paper sheet with no waste when a plurality of sheets of papers are continuously conveyed and images are formed on both surfaces of the paper sheets and to realize miniaturization of the device and reduction in manufacturing costs by making the constitution of a conveying mechanism for reversing the paper sheets simple and inexpensive. SOLUTION: The image formation device has a plurality of reversal parts 23, 24 for reversing the paper sheets 3 in order to form the image on both surfaces of the paper sheets 3. When the paper sheets 3 are simultaneously fed out from a plurality of reversal parts 23, 24, the device has a conveying route where the paper sheets 3 become the state that they are conveyed with a predetermined gap in the same order as before they are fed into the reversal parts 23, 24 when the paper sheets 3 fed out from the respective reversal parts 23, 24 are merged at a conveying passage at the feed out side. The image formation device has a conveying route where the paper sheets 3 become the state that they are approximately simultaneously fed to a plurality of respective reversal parts 23, 24 when a plurality of sheets of paper 3 are continuously conveyed.
