Fixation is satisfactorily fixed at a low power capacity. From low-speed to high-speed image forming devices, it has mold release characteristics in a wide temperature range, and has excellent offset resistance, blocking resistance, fluidity, no fog, and high-density and high-definition images. An electrostatic charge image developing toner is provided. A toner containing at least a polyester resin, a colorant, a release agent, hydrophobic silica, and titanium oxide, the toner particles of the toner having a wax component in a toner cross-section observation using a transmission electron microscope The amount of WAX dispersed in the form of islands and present in the vicinity of the surface is 2 to 10 wt% with respect to all components in the toner measured by total reflection infrared spectroscopy, and the volume average particle diameter (Dv of the toner) ) Is 4.0 to 6.0 μm, and the toner particle shape factor SF-1 is 140 to 200.
