    Abstract: PURPOSE: To provide a novel electrostatic toner capable of being rapidly and highly charged and having a charge stabilizer having a usable technical property to hold a charge constant at a high level. CONSTITUTION: This electrostatic toner contains a phenacyl derivative shown by the formula as a charge stabilizer. In the formula, ring A can be benzo- condensed or cyclized, HET is the positively charged group of a heterocyclic ring resulting from the pyrazole series, imidazole series, pyridine series, quinoline series or isoquinoline series, L is 1-8C alkylene groups, R is hydrogen atom, 1-6C alkyls, phenyl, etc., and An is the equivalent of anion.

    Abstract: PURPOSE: To produce a novel electrostatic toner containing polyamine as a charge stabilizer. CONSTITUTION: In the electrostatic toner, a polymer binder and a polyamine (average mol.wt. is 150-15000) as the charge stabilizer are incorporated, and nitrogen atoms are separated each other with 1-13C alkylene group or phenylene group which may be substituted, and 1-13C alkyl, phenyl, 1-10C alkanoyl, benzoyl, 1-6C alkylcarbamoyl, phenylcarbamoyl group or a group expressed by formula CO-L-CO are incorporated as a substituent group, and in a case of the later, a crosslinkage of two-polyamine unit is generated.
