PURPOSE:To easily control the electrostatic charge amount of the titled toner by incorporating 0.01-10pts.wt. the compd. having the composition shown by a prescribed formula based on 100pts.wt. of a resin component. CONSTITUTION:The titled toner contains 0.01-10pts.wt. the compd. shown by formula I based on 100pts.wt. of the resin component. In the formula, R<1> and R<3> are each shown by formula II (wherein R<5> is 1-18C alkyl, alkenyl group, or aralkyl or aryl group in which an aromatic ring may be substituted), R<2> and R<4> are each hydrogen or halogen atom, nitro, 1-18C alkyl, alkenyl, aralkyl, aryl or alkoxy group, X and Y are each -O-, -COO-, -S- or -NR<6>- group (wherein R<6> is hydrogen atom or 1-4C alkyl group), M is scandium, titanium, vanadium, manganese, nickel, or zinc, A is hydrogen atom or sodium, potassium, ammonium or an org. a ammonium, (l), (m), (n) or (p) are each 1 or 2. |
