ABSTRACT:
In a method of processing a silver halide photosensitive material wherein the exposed silver halide photosensitive material is developed with a developer containing a developing agent in two or more developing tanks, the first developing replenisher mainly comprising the developing agent is fed into a prior tank and the second developing replenisher mainly comprising an alkali is fed into a posterior tank to make pH of the developer in the posterior tank higher than that in the prior tank.
Also in a method of processing a silver halide photosensitive material wherein the exposed silver halide photosensitive material is developed by passing it through a developing passageway consisting of two or more processing chambers containing a developer and connected with one another, the first developing replenisher mainly comprising a developing agent is fed into a prior chamber, the second developing replenisher mainly comprising an alkali is fed into a posterior chamber and the developer flows in the same direction an that of the movement of the photosensitive material.
According to the methods, fogging can be inhibited without reducing the sensitivity of the photosensitive material.
