PROBLEM TO BE SOLVED: To provide a heat developing device by which a visible image whose density is always stabilized is obtained regardless of the processing number of film by suppressing the temperature lowering of a guide roller and also the miniaturization and the reduction of the cost of a device are realized. SOLUTION: The heat developing device is provided with a heating member 14 to heat the film F possessing a latent image and several guide members 16 arranged so as to be opposed to the heating member, and the visible image is obtained by performing heat development while pressing and feeding the film between the guide member and the heating member. Since a heat storage roller 18 by which the temperature lowering of the guide member is suppressed is provided at least at one part of the guide member, the temperature lowering of the guide member is suppressed, so that the density lowering of the film is prevented regardless of the heat development processing number of the film.
