<p>PURPOSE:To obtain toner and a developer excellent in durability and environmental resistance. CONSTITUTION:A nickel dithiolate complex represented by the formula is incorporated into the toner of an electrostatic charge image developer based on a resin and a colorant to obtain the objective toner and the objective electrostatic charge image developer contains this toner and a carrier. In the formula, X<+> is an H ion or a cation, (n) is 1 or 2, each of R1 and R2 which may be different is H, 1-20C alkyl, optionally substd. phenyl, an optionally substd. alicyclic group, nitro, nitrile, ester, alkoxy, amino, chalcogenide or halogen, R1 and R2 may form a ring by bonding to each other and both of them are not optionally substd. phenyl.</p> |
