Heat developing device for locally heat developing a dry photosensitive film
 A heat developing device for locally heat developing a dry photosensitive film composed of a heating unit for locally heating a portion to be heat-developed of the photosensitive film and a cooling unit surrounding the heating unit and placed in contact with the periphery of the portion to be heat-developed of the photosensitive film. The cooling unit functions to prevent the thermal effect applied to the heat-developing portion of the photosensitive film from being transmitted to the remainder of the photosensitive film.
