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.
