Disclosed is a nonaqueous ink jet ink that is suitable for printing (scratch resistance and resistance to alcohol wiping) on recording media of plastics such as polyvinyl chloride, is highly safe, can be used without posing any problem of odor, has excellent properties of ink ejection from an ink jet head, and can realize a good printed image quality. Also disclosed are a process for producing a nonaqueous ink jet ink and an ink jet recording method using the nonaqueous ink jet ink. The process for producing a nonaqueous ink jet ink is a process for producing a nonaqueous ink jet ink containing at least an organic solvent, a pigment, and a fixing resin. The process is characterized in that the fixing resin satisfies a b/a value of not more than 0.020 wherein a represents the tall of integrated values of areas of all of peaks derived from the fixing resin among all of peaks detected in a proton nuclear magnetic resonance analysis; and b represents the total of integrated values of areas of all of peaks derived from the compounds other than the fixing resin.
