Abstract
An electrostatic latent image developing toner includes toner particles each including a toner core and a shell layer covering a surface of the toner core. The shell layer contains a hydrophilic thermosetting resin and a hydrophobic thermoplastic resin. The hydrophobic thermoplastic resin is exposed at surfaces of the toner particles. In a preferable configuration of the shell layer, a plurality of blocks substantially formed from the hydrophobic thermoplastic resin are connected to one another through a junction portion substantially formed from the hydrophilic thermosetting resin.
