The guanidine compound etc. of 5-87145 are known. However, many of such development accelerators tend to increase the fog of the photographic light-sensitive material, and also tend to worsen other photographic characteristics such as graininess. In addition, some of them have the drawback of poor running stability, and under the present circumstances, few of them have been put into practical use. On the other hand, there is also a method of increasing the sensitivity by including these accelerators in the silver halide photographic light-sensitive material, but it deteriorates the storage stability of the silver halide photographic light-sensitive material, and this tendency is remarkable especially at high temperature and high humidity. The current situation is that I cannot bear it.

For example, it may be added to the hydrophilic colloid solution as a solution of an organic solvent such as alcohols (methanol, ethanol, propanol, fluorinated alcohol), ketones (acetone, methyl ethyl ketone), dimethylacetamide, dimethyl sulfoxide, methyl cellosolve. When it is added to the silver halide emulsion layer, it can be added at any time during emulsion preparation, but it is preferably added after the completion of chemical ripening and before coating. Particularly preferably, it is added to the coating solution prepared for coating. The amount added is 1.0 × 10 ^{−5 to} 1.0 × 10 ⁻² mol per mol of silver halide,
It is more preferably used in the range of 5.0 × 10 ^{−4 to} 5.0 × 10 ⁻³ mol. When the compound is added to the developing solution, it is preferably 5 × 10 ^{−3 to} 0.2 mol per 1 l of the developing solution.
