PURPOSE:To broaden a general use of the titled toner and to make easy to control characteristics of the titled toner by incorporating to the titled toner, a polymer or a copolymer contg. a long chain alkylene and acid anhydride or its derivative as a monomeric units. CONSTITUTION:The titled toner composition is prepared from the polymer or the copolymer contg. the long chain alkylene and a cyclic acid anhydride composed of succinic acid or maleic acid as the monomeric units. The above described polymer or copolymer has a weight average molecular weight of 3,000-100,000. The compounding amount of the above described polymer or copolymer is 1-30wt% on the weight basis of the titled toner. If a terpolymer composed of the above described monomer and another comonomer is used to the titled toner, the prescribed compounding ratio of the terpolymer to the titled toner lies in the prescribed range. |
