Abstract

A method for controlling pressure applied to a press roller unit during image development in which a photosensitive sheet coated with microcapsules containing photosetting materials and coloring dyes is exposed to light and then superimposed on an image receiving sheet so that the superimposed sheets are pressed together so as to form an image on the image receiving sheet. The pressure is applied or released under the controls of the timers.
