Abstract
A silver halide photographic emulsion comprising silver halide grains which are formed while iodide ions are rapidly being generated from an iodide ion-releasing agent represented by Formula (I) below, and which are chemically sensitized with a selenium sensitizer. Formula (I) EQU R--I where R represents a monovalent organic residue which releases the iodine atom in the form of iodide ions upon reacting with a base and/or a nucleophilic reagent.
