摘要： An electrostatic charge image developing toner includes toner particles, and an external additive. The toner particles are (1) prepared by forming aggregated particles by aggregating resin particles in a raw material dispersion in which the resin particles are dispersed, and causing the aggregated particles to coalesce by heating an aggregated particle dispersion in which the aggregated particles are dispersed so as to form the toner particles, or (2) obtained by kneading and pulverizing a material including a binder resin and a release agent, and the external additive is silica particles having an average diameter in the range of 100 nm to 500 nm, an average circularity in the range of 0.5 to 0.85, and an average of a ratio of a circle-equivalent diameter Da obtained by plane image analysis to a maximum height H obtained by 3-D image analysis of greater than 1.5 and less than 1.9.
