A thermal developing type photosensitive pressure sensitive recording medium records an image and transfers the image onto an image receiving medium. The image recording medium includes a substrate, microcapsules and binder. The microcapsules are formed on the substrate, and encapsulate therein dye and polymerizable compound. A latent image is formed in a combination of the microcapsules by changing mechanical strength thereof upon photopolymerization of the polymerizable compound for forming cured and non-cured microcapsules. The dye flows out of the non-cured microcapsules and is transferred onto an image receiving layer by rupturing the non-cured microcapsules upon pressure application. The binder fixes the microcapsules onto the substrate. The binder contains a pressure sensitive adhesive agent. A portion of the image receiving layer, which portion being out of the image transferred area is adhesively removed from a base sheet of the image receiving medium and bonded to the image recording medium when the binder is pressed into direct contacted with the image receiving layer. If dye exists between the binder and the image receiving layer, such removal is restrained.
