摘要： PURPOSE:To produce a silver halide emulsion which is a constituent of a photosensitive material that has high sensitivity, high developing processability, excellent preservable properties and low dependence on processing and enables low exhaustion of processing solutions at the time of running its processing by adding silver halide fine particles contg. silver iodide to the emulsion in a specified condition and chemically sensitizing the emulsion with a selenium compound. CONSTITUTION:The production of the silver halide emulsion is performed by adding silver halide fine particles contg. silver iodide to the emulsion in a condition of =10%, preferably >=20% and most desirably 100%. A specifically excellent effect on an emulsion is realized by applying this sensitization with selenium or selenium- sulfur to the emulsion, which is obtained by forming a very thin layer having high iodide content on the surface of each of the silver halide fine particles with the dissolution of fine particles having high iodide content in a low pAg condition.
