Claim:
1. An electrostatic charge image developing toner comprising: a toner particle that has a sea-island structure including a sea portion containing a binder resin and an island portion containing a release agent and having at least two distinct peaks having maximum values of distribution of a degree of uneven distribution B of the island portion shown by the following Equation (1): wherein: in Equation (1), D represents an equivalent circle diameter (μm) of the toner particle obtained by cross section observation of the toner particle, and d represents a distance (μm) between the center of gravity of the toner particle and the center of gravity of the island portion containing the release agent obtained by cross section observation of the toner particle, and all of the maximum values of distribution of the degree of uneven distribution B of the toner particle are in a range of 0.35 to 1.00.
