<p>PROBLEM TO BE SOLVED: To prevent image formation processing efficiency from being lowered by double feed of recording material. SOLUTION: A paper feeding part is provided with a separating part 30. When recording paper 12A, 12B are taken out in an overlapped state from a tray 20, at the time of the recording paper 12A, 12B reaching a clamping position by a driving roller 44 and a retarding roller 46, the rotation of the retarding roller 46 is stooped, and only the recording paper 12A is delivered toward a carrier roller 34. The driving roller 44 is then stopped once, and after the recording paper 12A is delivered to a double-side printing part 16, the driving roller 44 is driven again to feed the remaining recording paper 12B to the double-side printing part 16.</p> |
