PURPOSE: To obtain the image forming material having an excellent preservable property, high UV color developing density and high visible light fixing performance.

CONSTITUTION: A photosensitive layer which is a photosensitive layer contg. (a) a photooxidizing agent which forms an oxidative material by irradiation with UV rays, (b) a dye leuco substance which develops a color by the oxidative material, (c) a photoreducing agent which forms a reducing agent by irradiation with visible light, (d) a hydrogen donator which supplies hydrogen to this photoreducing agent, (e) a binder, and (f) a plasticizer and contains the plasticizer and hydrogen donator at a relatively high ratio to the ratio of the binder is provided on a base material. A light transmissible layer is laminated on this photosensitive layer. The relatively large amt. of the plasticizer and the hydrogen donator are incorporated into the binder, by which the high UV color developing density and the high visible light fixing performance are obtd. In addition, sticking is eliminated and the preservable property is enhanced by the light transmissible layer.
