发明名称 静電荷像現像用トナー
摘要 Disclosed is a toner for electrostatic image development having excellent low-temperature fixability and high-temperature off-set resistance, attaining good image density, and having excellent homogeneity in image density. The toner comprises toner particles containing a binder resin which contains an amorphous resin (A) and an amorphous polyester resin (B) different from the resin (A) and a colorant, wherein the toner particles have a domain-matrix structure having the resin (B) as a domain phase dispersed in a matrix phase comprising the resin (A), and in a cross-sectional image of the toner particles, the number average domain diameter of the domain phase of the 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%.
