Abstract: PURPOSE: To make a toner excellent in electrostatic chargeability by incorporating a specified compd. as an electric charge stabilizer into the toner. CONSTITUTION: This toner consists of a polymer binder having 40-200 deg.C softening temp. and 0.01-2wt.% electric charge stabilizer based on the amt. of this toner or further contains a coloring component and at least one kind of compd. represented by formula I is contained as the electric charge stabilizer. In the formula, R is Cl or methyl, preferably methyl, R is 4-22C alkyl, benzyl or 2-phenylethyl, preferably 10-22C, especially 12-22C alkyl, A is an equiv. anion, (n) is 0, 1 or 2, preferably O or 1, (m) is 1 or 2 and (r) is 1 or 2. This toner is excellent in electrostatic chargeability.
