Is applied to concentrated liquid photographic processing compositions commonly used in the art. For one development processing step, usually, a developer composition and a photographic processing composition for a silver removal step are assembled as a kit, and the latter can be further divided into a bleaching composition and a fixing composition. In many cases, the containers of the present invention can be used in any of these compositions. In addition to these, there are additional processing baths such as a washing substitute stabilizing bath and an image stabilizing bath, and a photographic processing agent for such a processing bath may be contained. Additional processing baths such as a washing substitute stabilizing bath and an image stabilizing bath are not necessarily the object of the present invention because their concentration is extremely low as compared with the processing baths in the developing step and the silver removing step. Photoprocessing plastic containers can be used. In many cases, a plurality of containers packaged together are of the same shape and volume, and are composed of three containers each filled with a color developing composition, a bleaching composition, and a fixing composition. However, the present invention is not limited to this, and a solution filled with, for example, a stabilizing bath composition or a preservative composition may be added as needed.
