Claim Text:
1. A toner for electrostatic image development comprising toner particles containing a binder resin which contains an amorphous resin (A) and an amorphous polyester resin (B) that is different from the amorphous resin (A) and a colorant, wherein said toner particles have a domain-matrix structure having the amorphous polyester resin (B) as a domain phase dispersed in a matrix phase comprising the amorphous resin (A), wherein in a cross-sectional observation image of the toner particles, the number average domain diameter of the domain phase of the amorphous polyester resin (B) having a domain diameter of 100 nm or more is 100 to 200 nm and an area ratio of the domain phase having a domain diameter of 500 nm or more relative to the total area of the domain phase is 0 to 10%, and wherein a domain phase C including the colorant is further dispersed in the matrix phase comprising the amorphous resin (A), and the number average domain diameter of the domain phase C including the colorant is 10 to 300 nm.
