PURPOSE:To obtain the titled composition capable of preventing offset without applying any offset preventing solution, by using a specific polyester resin as a main component of a binding resin of the titled composition, and by incorporating at least two kinds of electric charge controlling agents to the titled composition. CONSTITUTION:The main component of the binding resin contd. in the titled composition is composed of the polyester resin obtd. by effecting a condensation polymerization of a diol component shown by formula I, a bivalent carboxylic acid or its acid anhydride or its lower alkylester, a trivalent or more polyhydric alcohol, and a trivalent or more carboxylic acid or its acid anhydride or its lower alkylester. The polyester resin has >=1.2 OHV/AV (wherein, AV is the acid value and OHV is the hydroxyl value). The titled composition contains at least two kinds of the electric charge controlling agents. Thus, the sufficiently broad nonoffset range is obtd. by the titled composition. |
