<p>PROBLEM TO BE SOLVED: To obtain a novel organosilicon compound that comprises a specific ammonium salt organosilicon compound, is useful as a charge controller and can give a toner for the static image developer and a dry-process developer for static charge image excellent in static charge behavior, resistance to moisture absorption and stability. SOLUTION: This compound is a novel quaternary ammonium salt organosilicon compound represented by formula 1 [R<1> and R<2> are each a 1-6C alkyl, a (substituted) phenyl; R<3> is a (substituted) alkyl, alicyclic alkyl, a (substituted) phenyl, a (substituted) benzyl; R<4> is H, a halogen, nitro, cyano, trifluoromethyl; Me is methyl] and it is used as a charge controller to produce a toner for static charge image development and a dry-type developing agent for static charge images excellent in the static behavior, resistance to moisture absorption and the stability with time. This compound is produced by allowing a silylbis(propyl)ammonium chloride represented by formula II to react with sodium (potassium) tetraphenylborate derivative of formula III.</p> |
