Abstract
An electrostatic latent image developing toner includes a plurality of toner particles each including a toner mother particle and an external additive attached to a surface of the toner mother particle. The external additive includes a plurality of resin particles each containing first temperature responsive polymer domains and second temperature responsive polymer domains. The second temperature responsive polymer domains have a lower critical solution temperature (LCST) higher than that of the first temperature responsive polymer domains.
