摘要： A latent image of a medical image is recorded on a heat development photosensitive material. Development is carried out on the photosensitive material, on which the latent image has been recorded, and the medical image having multiple gradation levels is thereby obtained. The development is carried out at a heating temperature falling within the range of 120.+-.10.degree. C., at a width-direction temperature accuracy falling within the range of .+-.3.degree. C., and for a development time falling within the range of 5 seconds to 30 seconds. In the heat development technique, the processing time is thus set to be a practically acceptable short time, noise is reduced, and a medical image having good image quality is obtained.
