PROBLEM TO BE SOLVED: To form an excellent image, regardless of outside air temp. by providing a heating means on an exposure base which has a surface facing the light irradiation surface of an exposure head and on which a photosensitive recording medium is placed. SOLUTION: A preheater 64a is stuck to the side facing the exposure head 20 of the exposure base 66 by an adhesive and comes into surface contact with a microcapsule sheet 37 carried/placed on the exposure base 66. Then, the microcapsule sheet 37 is heated by the preheater 64a having a positive temperature coefficient. Further, as a fixing means, a postheater 64b similar to the preheater 64a is provided. The postheater 64b is constituted so that it is arranged in a state where its top end surface is in contact with the bottom surface of a roller, to heat the microcapsule sheet 37 after being developed. Therefore, the photosensitive recording material on the exposure base 66 is heated to a prescribed temp., without being affected by the outdoor air temp. and exposed in the state where fixed high sensitivity is provided. |
