Toner, toner production method and a two-component developer
2005
Resin particles, the colorant particles and wax particles were mixed aggregate in an aqueous, a toner or two-component developer obtained by heating, the weight average molecular weight measured by gel permeation chromatography of the resin particles (GPC) is 10000-60000, is a ratio of weight average molecular weight to number average molecular weight of 1.5 to 6, and the wax comprises at least a first wax and a second wax, DSC of the first wax endothermic peak temperature by law (melting point Tm1 (℃)) is a is 50~90 ℃, the second endothermic peak temperature by DSC method of wax (melting point Tmw2 (℃)) is, high temperature 5~50 ℃ more than Tmw1 it is. Thus, to create a toner having a small particle diameter having a sharp particle size distribution classification step is unnecessary, it is long life, provides a toner or two-component developer spots and scattering can be prevented in the time of transfer.
