ABSTRACT:
An image recording apparatus having reversal feed means for feeding an elongated photosensitive sheet in a reverse direction. The photosensitive sheet undergoes exposure operation and a pressure developing operation. Since unexposed zone is positioned subsequent to the exposure zone, the unexposed zone is also positioned at downstream side of the exposure portion by the pressure developing operation to the preceeding exposure zone. The reversal feed means is adapted for moving an unexposed zone of the photosensitive sheet positioned at downstream side of the exposure portion to an upstream side thereof. A sheet nip releasing mechanism is provided in the apparatus for releasing sheet nipping force given by feed rollers during the reversal sheet feeding. Further, a shutter mechanism is provided for avoiding light irradiation to the unexposed zone during the reverse travel.
