A process for thermally developing a photothermographic media within an enclosed processor comprising the steps of transporting a photothermographic element with a latent image thereon to a thermal heating element (11) comprising a rounded heating element such as a drum, placing said photothermographic media with a latent image into contact with said drum, heating said photothermographic media with a latent image thereon with said drum to generate a photothermographic media with a visible image thereon, then removing said media with a visible image thereon, said process comprising venting gas from at least two separate areas within said processor, said at least two areas including a first vent (A) at a position above the axis of the heating drum, and a second vent (8) at a position sufficiently near a point on the drum where the photothermographic media with a visible image thereon is removed from the drum so that at least some vapor material leaving said photothermographic media with a visible image thereon exits through said second vent.
L'invention se rapporte à un procédé de développement thermique d'un support photothermographique dans un processeur fermé consistant à transporter un élément photothermographique comportant une image latente vers un élément de traitement thermique (11) comprenant un élément chauffant sphérique, tel qu'un tambour, à mettre en contact ce support photothermographique comportant une image latente avec le tambour, à chauffer ce support photothermographique comportant une image latente avec le tambour afin de générer un support photothermographique comportant une image visible, puis à retirer ce support comportant une image visible. Ce procédé consiste également à décharger un gas à partir d'au moins deux zones séparées se trouvant dans le processeur, ces deux zones au moins comprenant un premier conduit (A) placé au-dessus de l'axe du tambour chauffant, et un second conduit (8) se trouvant suffisament près d'un point du tambour où le support photothermographique comportant une image visible est retiré du tambour de sorte qu'au moins de la vapeur s'échappant du support photothermographique comporant une image visible sorte par ce second conduit.
