PURPOSE:To prevent the contamination of an automatic developing machine by adding a specified compound to a developer so as to prevent the formation of insoluble matter in the developer. CONSTITUTION:A compound represented by the formula (where R is H or alkyl) is added to a developer for processing a silver halide photographic sensitive material. When the sensitive material is processed with the developer in a small-sized automatic developing machine, the formation of isoluble matter in the developer can be prevented, so the contamination of the developing machine can be prevented and the film can be processed without staining. |
