PURPOSE:To prevent a paper from being mixed with one-face copied paper by feeding a paper from an intermediate tray unless there is a paper in a subordinate intermediate tray during reverse-face copying operation and then feeding a paper from the subordinate intermediate tray when there is the paper in the subordinate intermediate tray. CONSTITUTION:The subordinate intermediate tray 81 is arranged rockingly around a both-face copying conveyance path 34 as a fulcrum and the end bottom face on the side of an inverting paper conveyance path 35 contacts a cam roller 82. When a paper is fed from the subordinate intermediate tray 81, the cam roller 82 rotates and the side end part of the inverting paper conveyance path 35 of the subordinate intermediate tray 81 moves up. The paper stacked in the subordinate intermediate tray 81 by this operation abuts on a subordinate intermediate tray part paper feed roller 84 and is fed toward the inverting paper conveyance path 35. A changeover claw 83 for one-face copied paper is arranged rockingly at part of the both-face copying conveyance path 34. Said changeover claw 83 is a one-face copied paper switching means and guides the one-face copied paper to an intermediate tray 22 or the subordinate intermediate tray 81. |
