Electrostatic charge image developing toner

An electrostatic charge image developing toner comprising:

• toner base particles containing a binder resin and a metallic gloss pigment;
• and
• an external additive containing lanthanum-containing strontium titanate particles,
• wherein the lanthanum-containing strontium titanate particles are surface-treated with a coupling agent represented by the following general formula (1):
• X-M(OR)3 (1)
• wherein M represents titanium or silicon,
• X represents an alkyl group having 4 to 12 carbon atoms, and
• Rs each independently represent a methyl group or an ethyl group,
• the lanthanum-containing strontium titanate particles surface-treated with the coupling agent have a carbon content of 1.0 to 8.0% by mass,
• the lanthanum-containing strontium titanate particles have a number average primary particle size of 8 to 40 nm, and an amount of the lanthanum-containing strontium titanate particles is 0.05 to 2.0% by mass with respect to an amount of the toner base particles.
