要がある。2. Description of the Related Art In a copying machine of this type, if development is carried out at a low temperature in a heating and developing section, development becomes insufficient, and a latent image is not sufficiently developed and color development becomes light. Conversely, when development is carried out at a high temperature, the color-forming components are thermally decomposed and the color development becomes thin, so that an appropriate density cannot be obtained. For this reason, in the heating and developing section, 130 to
It is necessary to carry out development at a temperature suitable for development of a photothermographic paper of 150 ° C.
