Sheet feeding device for a duplex image forming apparatus
 The intermediate sheet feeding device for a duplex image forming apparatus includes: an intermediate tray; an sheet input conveyance path to the intermediate tray; a sheet output conveyance path from the intermediate tray; the sheet input conveyance path and the sheet output conveyance path being arranged to intersect each other at one end of the intermediate sheet tray; a conveying roller provided along the conveyance path from the image processing portion to the intermediate tray; and a conveyance controlling means which controls the conveying roller so as to convey the sheet at a speed lower than that when the sheet advances through the image processing portion and so that a short-sized sheet is conveyed slower than a long-sized sheet. Further, a configuration for preventing sheet curl includes: a presser member for pressing the rear end of a sheet input above the intermediate tray against the intermediate tray; and a lift stopper member pivotally supported at an axle below the input roller so as to inhibit the pop-up of the rear ends of sheets.
