An electrostatic charge image developing toner excellent in transfer maintenance is provided. Toner particles having an average circularity of 0.91 to 0.98, silica particles externally added to the toner particles, and an average primary particle size externally added to the toner particles of 10 nm or more. Strontium titanate particles having an average circularity of 100 nm or less, an average circularity of primary particles of 0.82 or more and 0.94 or less, and a circularity of 84% of primary particles that is greater than 0.92 Toner for image development.
