Toner, image forming method, and process cartridge

摘要

In a toner having toner particles containing at least a binder resin, a colorant and a release agent, the toner has a loss tangent (tan delta) which has a minimum value 1 and a maximum value 1 at from 70° C. or more to less than 110° C. and has a maximum value 2 at from 140° C. or more to less than 200° C. and has a loss elastic modulus at 140° C., G''(140° C.), which is: 1.0x10⁴ dN/m2<=G''(140° C.)<=2.0x10⁵ dN/m²; and the binder resin is chiefly composed of a vinyl type copolymer. This can provide a toner with which images kept to have gloss within a preferable state can be obtained without changing fixing speed and fixing temperature even when transfer materials of different types are used.
