Patent ID: 8592121

Claim:
An electrostatic image developing toner for pressure fixing, comprising: a binder resin comprising two kinds of resin particles fused together to form a sea-island structure, wherein an island phase contained in the sea-island structure consists of a plurality of island phases, a difference between a glass transition temperature of the resin particles forming a sea phase contained in the sea-island structure and a glass transition temperature of the resin particles forming the island phase is about 30° C. or more, both of the glass transition temperatures of the resin particles forming the sea phase and the resin particles forming the island phase are less than about 55° C., and the island phase has a major axis of about 150 nm or less, the major axis of the island phase being determined by observing an arbitrary section of the electrostatic image developing toner and calculating an average major axis of a plurality of island phases observed in the arbitrary section.
