摘要：
An image forming apparatus includes a finite length recirculating duplex path (69) without a duplex tray and having an inverter (68). A receiving sheet is delayed in the inverter (68) by a time which is variable in order to vary the recirculating path time. Preferably, the time is varied according to the length of receiving sheet used so that maximum usage can be made of the image forming apparatus.
A preferred inverter includes entrance (23) and exit (25) nips and a stop (3) at the end of a paper chute. The stop (3) is positioned to receive the leading edge of a sheet fed into the chute and hold the sheet through a variable time delay. The stop (3) is then moved toward the exit nip at the end of the time delay to begin to move the receiving sheet out of the inverter. The receiving position of the stop (3) is variable to receive sheets of different intrack length.
