More Information
Summary:The invention provides an electrostatic charge image developing toner capable of forming halftone images with strong image strength for recording medium with obvious surface unevenness. The electrostatic charge image developing toner includes toner particles containing a binder resin containing a polyester resin forming a sea part and a vinyl resin forming an island part of a sea-island structure, a first release agent existing in the sea part in a domain state, and a second release agent existing in the island part in a domain state, wherein when a cross-sectional area of the second release agent is set to A1 and a cross-sectional area of the first release agent is set to B1 in a cross section of the toner particles, a relationship of 0.2<=A1/B1<=0.8 is satisfied. The invention further provides an electrostatic charge image developer and a toner cartridge.
