摘要:
An electrostatic charge image developing toner, includes toner particles containing a binder resin including a polyester resin, a release agent including a hydrocarbon wax, and a styrene (meth)acrylic resin, wherein 70% or more of the release agent is present within 800 nm from a surface of the toner particles, the styrene (meth)acrylic resin in the toner particles forms a domain having an average diameter from 0.3 μm to 0.8 μm, and a number ratio of the domain being in a range of ±0.1 μm of the average diameter is 65% or more.
