ABSTRACT:
An imaging device employing a continuous recording sheet which carries thereon a plurality of photo and pressure sensitive microcapsules. Each microcapsule contains therein a dye precursor and a photo-curable resin. By exposing the recording sheet to an optical image, a corresponding latent image is formed thereon with hardened and unhardened microcapsules. The unhardened microcapsules are ruptured by a pressure-developing means and dye precursors streamed out of the ruptured microcapsules react to developer coated on a separate cut-sheet type developer sheet. In order to prevent the pressure-developing means from being polluted by components of microcapsules of the recording sheet, all over the portion of the recording sheet, on which an optical image is not exposed, is fully exposed to a light to harden substantially whole microcapsules carried thereon.
