To prevent occurrence of water scale in a water rinse vessel at the time of processing a silver halide photographic sensitive material with an automatic developing machine and preventing precipitation of aluminum hydroxide in the rinse vessel at the time of using a fixing solution contg. an aluminum salt.

This silver halide photographic sensitive material is processed with the automatic developing machine comprising a developing section, a fixing section, and a rinsing section and further, a means for supplying the rinsing water into the rinsing section and a means for adding an aqueous sloution containing hydrogen peroxide and 5-sulfosalycilic acid or its salt each in a concentration of 2-20 mmol/l and 0.03-0.5 mmol/l in parallel to the rinse wateras replenished water into the rinse vessel.
