PROBLEM TO BE SOLVED: To provide a toner that satisfies demands for cleaning property, contamination prevention in a charging member, and followability to a solid image upon outputting a great number of images in a low temperature and low humidity environment, all in high levels in a capsule toner aiming to achieve both low-temperature fixability and heat-resistant storage property.SOLUTION: A toner includes: toner particles having a core-shell structure having a core comprising a binder resin and a shell comprising a polyester resin (A) formed on a surface of the core; and an external additive (A). The polyester resin (A) shows a dielectric loss tangent of 0.0070 or more and 0.0140 or less; and the toner contains the polyester resin (A) by 1.0 part by mass or more and 20.0 parts by mass or less with respect to 100.0 parts by mass of the binder resin. The external additive (A) comprises organic inorganic composite fine particles in which inorganic fine particles (a) are exposed on a surface of resin particles so as to form projections derived from the inorganic fine particles (a) on the surface; and an abundance of the inorganic fine particles (a) on the surface of the organic inorganic composite fine particles is 20% or more and 70% or less.SELECTED DRAWING: None |
