Patent ID: 7368213

Claim:
A toner, comprising: toner particles having a core-shell structure, and comprising: a binder resin; a colorant; and a release agent, wherein the toner satisfies the following relationship: ΔTm=Tm 1 −Tm 2 >10° C., wherein Tm 1 represents half efflux temperature of the toner and Tm 2 represents half efflux temperature of a toner which is prepared by melting and kneading the toner particles and wherein a content of the release agent in the area 0.3 μm deep down from the toner surface of the toner particles is from 7 to 30% by volume based on the entire area 0.3 μm deep down from the toner surface of the toner particles when the content is determined by Fourier Transform Infrared Spectroscopy Attenuated Total Reflection (FTIR-ATR) method.
