に転写し発色反応を起こさせることで達成されている。[Prior art] A technology for forming images by controlling the transferability of a transfer material using the photocurability of a photosensitive material is a film-like film coated with microcapsules encapsulating at least a coloring material and a photocurable material. This system uses a photoreceptor and transfer paper. Image formation begins by exposing the photoreceptor to light in the visible range at least once in a desired pattern, and then photocuring the microcapsules in the areas exposed to the light. The photocurable material is cured, and then the exposed surface of the photoconductor is brought into close contact with the transfer paper, and by applying pressure, the microcapsules containing the photocurable material that have not hardened are destroyed, and the color contained in the same microcapsules is destroyed. This is achieved by transferring the material to transfer paper and causing a color reaction.
