Abstract
Provided is an electrostatic charge image developing toner including: toner particles; and strontium titanate particles A and strontium titanate particles B having different average primary particle diameters from each other. The strontium titanate particles B have an average primary particle diameter Db of 10 nm to 100 nm. An average primary particle diameter Da of the strontium titanate particles A and the average primary particle diameter Db of the strontium titanate particles B satisfy a relationship of 10≤Da/Db≤100.
