TONER FOR DEVELOPING ELECTROSTATIC CHARGE IMAGE

摘要

PURPOSE:To obtain the toner excellent in fixability and anti-offsetting property and adaptable to the attainment of high copying speed and clear stable copying requested in recent years. CONSTITUTION:This toner contains a principal resin component consisting of a low mol.wt. polymer and a high mol.wt. polymer. The resin component has 40-80 deg.C glass transition temp., 100-200 deg.C softening point, the melt flow index of 0.5-10.0, 5X10<3>-1x10<5>dyn/cm<2> modulus G' of storage elasticity at 170 deg.C and the dynamic loss tangent tandelta of 1.0-4.0 at 170 deg.C.
