Abstract
Photographic silver halide photosensitive material is continuously processed through an automatic processor by passing the photosensitive material through a developing tank filled with a developer and then through a fixing tank filled with a fixer while supplying developer and fixer replenishers to the developing and fixing tanks in amounts corresponding to the processing quantity. The replenisher amount can be reduced by adding a chelating agent to the developer and its replenisher. Kits containing developer and fixer replenisher concentrates become empty at the same timing if the ratio of the volumes of developer and fixer replenishers prepared from their kits by diluting developer and fixer concentrates in the kits with water is substantially equal to the ratio of the amounts of developer and fixer replenishers supplied to the tanks.
