A toner obtained by water-based granulation using at least a polyester resin as a binder resin and having good pigment dispersibility, a method for producing the toner, and a toner masterbatch for the toner To provide. In a full-color electrophotographic toner obtained by suspending and granulating an oil phase of a toner material containing at least a binder resin and / or its precursor, a colorant and a release agent in an aqueous medium. The colorant is a masterbatch that is preliminarily dispersed in a masterbatch resin, and two or more types of resins having different viscosities are used as the masterbatch resin, and the storage elasticity at 90 ° C. of the resin R1 having the highest viscosity. The modulus G1 ′ is 8.0 × 10E4 to 5.0 × 10E5, and the storage modulus G2 ′ at 90 ° C. of the resin R2 having the lowest viscosity is 2.0 × 10E4 to 7.0 × 10E4. A toner for full color electrophotography. [Selection figure] None |
