摘要： A developer composition comprising a dihydroxybenzene developing agent, a sulfite ion, and an antisludging agent is diluted with water to prepare a developer for the development of photographic silver halide photosensitive material. The components of the composition are divided into a plurality of parts such that the antisludging agent and the dihydroxybenzene developing agent are added to separate parts which are kept apart during storage until they were combined to form the developer.
