ABSTRACT:
An image recording system wherein a capsule sheet carrying thereon a plurality of microcapsules each of which envelopes therein a developing agent pressed onto a sheet-shaped member desirably selected by a user to form a layer of a developing agent on the sheet-shaped member. Thereafter, a second capsule sheet coated with a plurality of microcapsules each of which envelopes therein a dye precursor and whose mechanical strength has been varied in accordance with the image to be recorded is pressed onto the sheet-shaped member with the layer of the developing agent. The microcapsules corresponding to the image to be recorded are ruptured and the dye precursors streamed out therefrom react to the developing agent on the sheet-shaped member to develop a visible image thereon.
