A method for processing an exposed silver halide color photographic photosensitive material is disclosed, which comprises the step of developing the exposed material with a color developer in a color development tank of an automatic developing apparatus, the developer in the developer tank being replenished with replenishing water and a solid color developing composition comprising a p-phenylenediamine color developing agent having a water-solubilizing group, wherein the replenishing amount of the water is 30 to 75 ml per m.sup.2 of the material processed and the replenishing amount of the color developing agent is 0.024 to 0.066 mol per liter of the replenishing amount of the water.

Method for processing a silver halide color photographic light-sensitive

A device to dissolve solid processing agents and to replenish the dissolved processing agents to an automatic processing apparatus for a silver halide photographic light-sensitive material which has a processing tank and a circulating path for a processing solution provided in the processing tank. The device includes a dissolving tank for storing a dissolved solution therein, and a processing solution supplier provided between the processing tank and the dissolving tank independent of the circulating path, which supplies the processing solution from the processing tank to the dissolving tank. The device further includes a replenisher to replenish the dissolved solution from the dissolving tank to the processing tank. The dissolving tank and the processing tank are communicated through another circulating path.
