Image recording apparatus

摘要

An image recording apparatus employs a photo- and pressure-sensitive heat-developable material having a substrate and a layer formed on the substrate from a material which is photo-sensitive and heat-developable and which enables the developed image to be fixed by a pressure, and an image receiving material. The photosensitive material and the image receiving material being adapted to be superposed one on the other and pressed to each other so as to transfer the image from the photosensitive material to the image receiving material. The pressing of these two materials is conducted by a means which includes a pair of pressing rolls for nipping the photosensitive material and the image receiving material therebetween; back-up rolls means having an axial length smaller than that of the pressing rolls and adapted for acting on at least one of the pressing rolls; and back-up roll pressing means capable of independently adjusting the pressure exerted by the back-up roll means on the pressing rolls.
