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 δ) 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: n 1.0×10 4 dN/m2≦G″(140° C.)≦2.0×10 5 dN/m 2 ; 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. |
