PURPOSE:To accelerate the speed of a color reaction between the image receiving sheet and an image forming agent by applying the film surface having a prescribed ruggedness with fine particles which are uniformly applied on the outer surfaces of adhesive resin particles having a specified particle size, with a substance capable of coloring by allowing it to react with the image forming agent. CONSTITUTION:The ruggedness having a pitch and depth of about 3-100mum is formed on the surface of a film 2 constituting of a base film, and reactive particles 3 having a smaller particle size than the pitch and depth of the uneven surface of the film 2, and a particle size of 0.01-10mum are uniformly applied on the uneven surface of the film 2 which is uniformly applied on a developing material on the outer surfaces of the adhesive resin particles. Thus, the effective surface area of the developing material increases, and the color reaction of the image receiving sheet rapidly progresses, thereby being improved in the optical density of an image. And, the peeling of the fine particle from the base film is prevented. |
