Zusammenfassung: | Provided is an electrostatic charge image developing toner which is capable of forming high-quality images for a long time period. An electrostatic charge image developing toner, including at least a binder resin, a colorant, and a mold release agent, wherein a coefficient of variation of volume particle size distribution of the toner particles is 18% or less, and in a particle shape distribution analysis made using a flow type particle image analyzer, when an equivalent circle average particle diameter of the toner particles is designated as D (µm), an average aspect ratio of toner particles having an equivalent circle particle diameter in the range of (D - 3) to (D - 2) (µm) is designated as AR(L), and an average aspect ratio of toner particles having an equivalent circle particle diameter in the range of (D + 3) to (D + 4) (µm) is designated as AR(H), the relationship represented by the following Expression (1) is satisfied.
