Toner for developing electrostatic latent image

Light-transmittable toner for developing an electrostatic latent image, in which at least a calixarene compound having a BET specific surface area of 15 to 80 m.sup.2 /g and inorganic fine particles having a BET specific surface area of 10 to 150 m.sup.2 /g are fixed and/or film-formed in a uniformly dispersed state on the surface of core particles mainly composed of linear polyester having a number-average molecular weight Mn of 2000 to 15000 and having a molecular-weight distribution (Mw/Mn) of not more than 3.

Toner for developing an electrostatic latent image, which is produced by mixing core particles mainly composed of thermoplastic resin, an organic charge-controlling agent having a BET specific surface area of 15 to 80 m.sup.2 /g and inorganic fine particles having a BET specific surface area of 10 to 150 m.sup.2 /g with each other, causing said organic charge-controlling agent and said inorganic fine particles to uniformly adhere to the surface of said core particles and then, fixing and/or film-forming said organic charge-controlling agent and said inorganic fine particles in a uniformly dispersed state on the surface of said core particles by a surface treating equipment.

Toner for developing an electrostatic latent image, which is produced by mixing core particles mainly composed of thermoplastic resin produced by the wet granulating process, an organic charge-controlling agent having a BET specific surface area of 15 to 80 m.sup.2 /g, and inorganic fine particles having a BET specific surface area of 10 to 150 m.sup.2 /g with each other and then, causing their mixture to aggregate and crushing an aggregate obtained by a surface treating equipment having a crushing function and at the same time, fixing said organic charge-controlling agent and said inorganic fine particles on the surface of the core particles.
