Toner for developing electrostatic image and fixing method

摘要

A toner for developing an electrostatic image is formed from toner particles containing at least a binder resin, a colorant and an organometallic compound. The binder resin in the toner particles has a tetrahydrofuran-insoluble (THF-insoluble) content of at most 5.0 wt.% based on the binder resin. The toner has a glass transition temperature of 50 DEG -80 DEG C. The toner further has storage modulus characteristics including a storage modulus at 80 DEG C. (G'80) of 1x104-5x106 [dyn/cm2], a storage modulus at 130 DEG C. (G'130) providing a ratio G'80/G'130 of 10-5x103, and a storage modulus curve showing a minimum (G'min) in a temperature region of 110 DEG -190 DEG C. The toner especially exhibits excellent low-temperature fixability, anti-high temperature offset characteristic, storage stability and color-miscibility.
