摘要： A toner having toner particles each comprising at least a binder resin, a wax, and a colorant is used in an image forming apparatus which has a fixing means comprising a belt-shaped heating member and a pressurizing member. The binder resin contains a resin formed by a reaction between an epoxy group of a vinyl resin (A) having the epoxy group and a carboxyl group of a resin (B) having at least a polyester unit and the carboxyl group. The toner has a storage elastic modulus at a temperature of 80° C. (G′ 80) in the range of 1×105 to 1×108 Pa and has a storage elastic modulus at a temperature of 160° C. (G′ 160) in the range of 1×101 to 1×104 Pa.

摘要： A toner, particularly a color toner suitable for full-color image formation through a substantially oil-less heat-pressure fixing device, is formed from at least a binder resin, a colorant and a wax. The toner has viscoelasticity including: a storage modulus at 80° C. (G′80) in a range of 1×106-1×1010 dN/m2, storage moduli at temperatures of 120-180° C. (G′120-180) in a range of 5×103-1×106 dN/m2, and loss tangents (tan &dgr;=G″/G′ as a ratio between G″ (loss modulus) and G′ (storage molecules)) including a loss tangent at 180° C. (tan &dgr;180) and a minimum of loss tangents over a temperature range of 120-180 ° C. (tan &dgr;min) satisfying 1≦tan &dgr;180/tan &dgr;min. The toner further exhibits a thermal behavior providing a heat-absorption curve according to differential scanning calorimetry (DSC) showing a maximum heat-absorption peak temperature in a range of 50-110° C. in a temperature range of 30-200° C.
