PURPOSE:To obtain the titled toner resin in triboelectrifiability controlling and uniform in electrifiability of each toner particles by incorporating a specific electrification control agent to the titled toner. CONSTITUTION:At least one kind of the compds. shown by formulas I and II is incorporated to a binding resin of the titled toner. In formula I, R1-R3 are each independently H, CH3, CCH3, NO2, Cl or SO2N(C2H5)2. In formula II, R9-R15 are each independently, H, CH3, SO3, COO or Cl, Me is Na, Ca, Ba, Sr or Mn, (n) and (l) are each an interger of 1-3. The titled toner is produced by for example, mixing the binding resin, the compd. I and/or the compd. II, a coloring agent and an another additives, followed by melt-kneading and pulverizing it. Thus, the titled toner having the good controllability for triboelectrification and especially, uniform electrifiability of each toner particles is obtd. |
