ABSTRACT:
The developing apparatus includes a plurality of successive processing chambers arranged for generally horizontal travel of a photographic material to be developed through the successive processing chambers. Each processing chamber is provided with a processing-fluid tank and guide structure for guiding the photographic material through the processing chamber. Transport roller pairs are arranged intermediate adjoining processing chambers for transporting photographic material from one chamber to the next. The last processing chamber is a washing chamber. The washing chamber includes a wash-water tank containing a body of wash water, with the upper surface of the body of wash water being maintained at a predetermined level. The washing chamber includes a guide structure for guiding photographic material through the washing chamber, including a submerging structure for causing transported photographic material to pass below the upper surface of the body of wash water. A pair of outfeed rollers, constituting transport rollers and/or squeeze-off rollers, is provided at the outlet end of the washing chamber for outfeed of washed photographic material. One roller is located above the other. A spray pipe is located intermediate the submerging structure and the outfeed rollers and is provided with a plurality of spray outlets oriented for spraying the wash water onto the peripheral surface of the upper one of the outfeed rollers.
