Title:

HEAT DEVELOPING APPARATUS

Document Type and Number:

Japanese Patent JP3731789

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a heat developing apparatus capable of preventing deposition by cooling, of vaporized substances contained in a gas within the apparatus, which are generated at a heat developing part from a photosensitive material, by which the fixation of the vaporized substances on a transporting roller or the like is avoided and the photosensitive material is protected from the contamination with the deposits when it is passed through them.
SOLUTION: A heat developing part is covered by a heat developing part housing body 11 so as to allow the heat developing part to be nearly closed space. A vacuum fan 301 is provided in the heat developing part housing body 11 and air within the nearly closed space, which is brought into contact with a layer containing a photosensitive composition of the photosensitive material A, is absorbed by using the vacuum fan 301 and is discharged to the outside of the heat developing part housing body 11. Thus, deposition by cooling of the vaporized substances contained in a gas within the apparatus is prevented and as the gas diffusion to the outside of the heat developing part housing body 11 is suppressed, fixation of the vaporized substances onto a transporting roller or the like is prevented and the photosensitive material is protected from the contamination when it is passed through them. Thus, the clean heat developing apparatus free from gas discharging to the outside of the apparatus is provided.
