Abstract
An electrostatic charge image developing toner includes a toner particle containing a binder resin, a release agent, a divalent metal, and a trivalent metal, in which the release agent has a domain diameter of 0.5 μm or greater and 1.5 μm or less.
Claims13
An electrostatic charge image developing toner comprising:
- a toner particle containing a binder resin, a release agent, a divalent metal, and a trivalent metal,
- wherein the release agent has a domain diameter of 0.5 μm or greater and 1.5 μm or less, the trivalent metal is aluminum (Al), and a content of the trivalent metal with respect to a mass of the toner particle is 0.5 mmol/kg or greater and 50 mmol/kg or less.
An electrostatic charge image developing toner comprising:
- a toner particle containing a binder resin, a release agent, a divalent metal, and a trivalent metal,
- wherein a ratio of a domain diameter of the release agent to a maximum diameter of the toner particle is 10% or greater and 30% or less, the trivalent metal is Al, and a content of the trivalent metal with respect to a mass of the toner particle is 0.5 mmol/kg or greater and 50 mmol/kg or less.
