In a method of drying a photographic light-sensitive material by use of drying air, the amount of light-sensitive material which can be processed within a predetermined time at a set temperature of the drying air is compared with the totalized amount of the light-sensitive material to be actually processed within the predetermined time, and, on the basis of the result of this comparison, the set temperature of the drying air can be adjusted. An apparatus for drying photographic light-sensitive material by use of drying air is arranged so that the amount of light-sensitive material to be actually processed within a predetermined time is detected by a detecting sensor and the thus-detected amount is compared with the amount of light-sensitive material which can be dried. If the amount of light-sensitive material to be actually processed exceeds the amount of light-sensitive material which can be processed, such a display is conducted that the apparatus is not ready for insertion of further light-sensitive material. Accordingly, the light-sensitive material can consistently be dried at a proper drying temperature.

Method of and apparatus for drying photographic light-sensitive material

An apparatus for detecting circulating liquid flow in a machine for automatically processing a photographic light-sensitive material is disclosed in which a branch pipe opened at a position higher than a liquid level of a processing liquid is vertically provided on the suction side of a circulating pump of a processing liquid circulating system provided outside a processing tank for circulating the processing liquid in the processing tank. A liquid level detecting electrode is provided in said opening portion so that the lower end of the electrode is positioned on the same level as or a position a little lower than the liquid level of the processing tank. A contact electrode is provided so as to be in contact with the processing liquid.
