Electrostatic image developing toner and preparation method thereof

   
   

An electrostatic image developing toner comprising a resin and a colorant is disclosed. 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 in an amount of 0.1 to 10.0 percent by weight; 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.

Показан тонер электростатического изображения превращаясь состоя из смолаы и colorant. Смолаа состоит из компонента полимерности polymerizable мономера имея приполюсную группу в количестве от 1.0 до 10.0 процентов весом, и компонента полимерности мономера polyfunctional polymerizable в количестве от 0.1 до 10.0 процентов весом; коэффициент (A/B) от от 0.5 до 20.0 процента; и или пик или плечо расположены в зону молекулярного веса 5.000 к 20.000, при котором а будет зоной кривого хроматографа в зоне молекулярного веса 60.000 к 1.000.000, основанную на измерении GCP компонента THF soluble тонера и б будет всей зоной кривого хроматографа.
