摘要：
A toner is provided including a binder resin, a colorant, and a release agent, which has a volume average particle diameter (Dv) of from 3 to 9 μm, and wherein the binder resin and the release agent form a sea-island structure in which the island formed of the release agent is dispersed in the sea formed of the binder resin in a cross-sectional image of the toner obtained by a transmission electron microscope (TEM), and the following relationships are satisfied: IB>IA and IB>IC, wherein each of IA, IB, and IC represents an area ratio (%) of the island in an outermost region (A) of the cross-sectional image of the toner, an intermediate region (B) thereof located under the outermost region (A), and an innermost region (C) thereof located under the intermediate region (B); and a method of preparing the toner.
