摘要:
An electrostatic latent image developing toner includes a plurality of toner particles each including a toner mother particle and inorganic particles attached to a surface of the toner mother particle. The toner mother particle includes a toner core (11) and a shell layer (12) covering a surface of the toner core (11). The shell layer (12) includes film-shaped first domains (12a) and particle-shaped second domains (12b). The first domains (12a) are substantially formed from a non-cross-linked resin. The second domains (12b) are substantially formed from a cross-linked resin. The cross-linked resin has a glass transition point higher by 40° C. or more than that of the non-cross-linked resin. The first domains (12a) have a surface adsorption force of at least 20.0 nN and no greater than 40.0 nN. The second domains (12b) have a surface adsorption force of at least 4.0 nN and less than 20.0 nN.
