Abstract

PURPOSE:To prevent occurrence of deposit and algae during washing, by adding chlorine dioxide in washing water which is not often refreshed. CONSTITUTION:After use, an automatic developing unit comes to a stop, and then, deposit and algae increases until the developing unit is again used at the next day, and accordingly, after a stop of the developing unit, a predetermined quantity of chlorine dioxide is added. Alternatively, a predetermined quantity thereof is added to washing water. It is particular effective to add it after the developing unit comes to a stop, and further, if the developing unit rests for a long time, the quantity of chlorine dioxide is adjusted correspondingly. The effective density of chlorine dioxide to be used, which differs in dependence upon a kind of a photosensitive material to be used, is 10 to 1000ppm, preferably 20 to 200ppm.

となる。In the washing water, gelatin in the light-sensitive material is slightly peeled off, and the temperature of the washing water is raised to improve the washing efficiency, so that favorable conditions are met for the generation of scale and algae. The scales and algae generated in the washing water adhere to the light-sensitive material being washed to reduce the image quality of the finished photograph.

【０００８】この様な条件に於ても、水垢や藻の発生が
