Abstract
An electrostatic latent image developing toner includes toner particles that each include a toner core and a shell layer disposed over a surface of the toner core. The shell layer contains a hydrophobic thermoplastic resin and a hydrophilic thermosetting resin. The hydrophobic thermoplastic resin is contained in an amount of no less than 0.2% by mass and no greater than 4.7% by mass relative to mass of the toner particles. The hydrophilic thermosetting resin is contained in an amount of no less than 0.01% by mass and no greater than 0.71% by mass relative to mass of the toner particles. The hydrophobic thermoplastic resin is exposed at a surface of each of the toner particles.
