Abstract
An electrostatic latent image developing toner includes toner particles that each include a toner core containing a binder resin and a shell layer disposed over a surface of the toner core. The binder resin includes a crystalline polyester resin and an amorphous polyester resin. The crystalline polyester resin has a melting point of at least 80° C. and no greater than 120° C. When the electrostatic latent image developing toner is measured using a differential scanning calorimeter, a glass transition point is observed in a first run but is not observed in a second run. The shell layer contains a resin including a thermosetting component and a thermoplastic component.
