Abstract:
A color toner characterized in that (i) it comprises a binding resin and a colorant, (ii) its storage elastic modulus at 90Â° C. (Gâ€²90) is not more than 6Ã—104 Pa, (iii) its storage elastic modulus at 140Â° C. (Gâ€²140) is not less than 5Ã—102 Pa, (iv) a temperature showing a maximum value of &dgr; in tan&dgr;=Gâ€³/Gâ€² (wherein Gâ€² is a storage elastic modulus of the color toner, and Gâ€³ is a loss elastic modulus of the color toner) exists in the range of 90-110Â° C., and (v) the maximum value of &dgr; is not less than 60Â° and not more than 90Â°.
