Abstract:
1. A heat developing apparatus, comprising: a heating section which heats a sheet film, which includes a support base and a photosensitive layer which is composed of heat developing photosensitive material coated on the support base, for no less than 5 seconds and no more than 10 seconds; and a cooling section which cools the heated sheet film, which is heated by the heating section, wherein the outer surface of the support base composes a support base side and the outer surface of the photosensitive layer composes a photosensitive layer side, and the heating section heats the sheet film from the support base side with the photosensitive layer side being open to an ambient atmosphere, and then the cooling section cools the heated sheet film from the support base side with the photosensitive layer side being open to the ambient atmosphere upwardly so that volatilized solvents from the photosensitive layer are not trapped.
