Abstract:
An electrostatic image developing toner comprising a resin and a colorant, wherein the resin comprises a polymerization component of a polymerizable monomer having a polar group in an amount of 1.0 to 10.0 percent by weight, and a polymerization component of a polyfunctional polymerizable monomer having two polymerizable functional groups in an amount of 0.1 to 10.0 percent by weight with reference to whole weight of polymerizable monomer; ratio (A/B) is from 0.5 to 20.0 percent; and either a peak or a shoulder is positioned in the molecular weight region of 5,000 to 20,000, wherein A is an area of a chromatograph curve in the molecular weight region of 60,000 to 1,000, 000, based on GCP measurement of a THF soluble component of toner and B is an entire area of the chromatograph curve.
