    摘要： To provide a toner that can keep its melt-sticking to sleeve from occurring and, even in double-sided printing, can keep high-temperature offset from occurring and obtain high-quality images on both the surface and the back. The toner comprises toner particles each of which contains a binder resin containing a resin formed by the reaction of i) a resin (A) having a softening point TA (° C.) of 70° C. to 105° C. and having a peak top of endothermic peaks at 55° C. to 120° C. with ii) a resin (B) having a softening point TB (° C.) of 120° C. to 160° C. and having a peak top of endothermic peaks at 55° C. to 120° C., and, in its viscoelasticity characteristics, has a storage elastic modulus at temperature 180° C. (G′180) of 3.0×103 Pa to 3.0×104 Pa, where the loss tangent tan δ has at least one peak having a peak top within the range of 50° C. to 70° C. and, when peak top temperature of the peak is represented by T(° C.), the loss tangent at T+10(° C.) [tan δ(T+10)] is 1.0 to 1.5 and the ratio of tan δ(T+10)/tan δ(110) is 0.8 to 1.5.

    摘要： The invention provides a toner which is excellent in its low-temperature fixing property and high-temperature offset resistance regardless of the types of paper, and constantly provides high-quality images regardless of environments and does not generate image defects even after prolonged use. In a master curve of the toner at a reference temperature of 150°C, a difference between a storage modulus at a frequency of 0.1 Hz and a storage modulus at a frequency of 1000 Hz is set in a rage from 0 to 2.5 × 10 5 Pa, where the activation energy determined from a shift factor is brought to a range from 50 to 130 kJ/mol.
