Abstract:
Provided is an electrostatic charge image developing toner, each toner particle including a core portion, a first shell layer, and a second shell layer, wherein the core portion contains a first polyester resin, a colorant, and a release agent, the first shell layer contains a second polyester resin and covers the core portion, the second shell layer contains a polymer of an aromatic vinyl monomer and a third polyester resin having an ethylenic unsaturated double bond that is polymerizable with the aromatic vinyl monomer, and covers the first shell layer, and a total amount of the first shell layer and the second shell layer is within a range of from 16% by weight to 40% by weight of the toner particle.
