Abstract
An electrostatic latent image developing toner includes a plurality of toner particles. The toner particles each have a toner mother particle and first inorganic oxide particles disposed on a surface of the toner mother particle. The first inorganic oxide particles are contained in the electrostatic latent image developing toner in an amount of no less than 1.0% by mass and no greater than 2.0% by mass relative to mass of the toner mother particles. The toner mother particles have an average roundness of no less than 0.960. The first inorganic oxide particles have an average major axis diameter of no less than 500 nm and no greater than 3,000 nm, an average minor axis diameter of no less than 100 nm and no greater than 250 nm, and an aspect ratio of no less than 2 and no greater than 20.
