摘要：
A toner for electrostatic image development includes: toner particles; Si-doped strontium titanate particles; and silica particles. The particle diameter D of at least one peak in a number-based particle size distribution of primary particles of the silica particles is larger than the number-based median diameter D50 of primary particles of the Si-doped strontium titanate particles.
