Abstract
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.
