Abstract:
Provided is a toner for developing electrostatic images which is less likely to cause toner ejection and is excellent in printing durability. The toner comprises colored resin particles and external additives, wherein the external additives comprise an external additive A and an external additive B; wherein the external additive A is silica particles being surface-hydrophobized with a specific hydrophobizing agent and having a specific number average particle diameter; and wherein the external additive B is silicone resin particles having a ratio (BS/TS) of a BET specific surface area (BS) to a theoretical specific surface area (TS) in a range of from 3.0 to 30.0, and having a specific number average particle diameter.

Claim (Index 1):
A toner for developing electrostatic images, comprising colored resin particles that comprises a binder resin, a colorant and a charge control agent, and external additives,\n wherein the external additives contain at least an external additive A and an external additive B; wherein the external additive A is silica particles being surface-hydrophobized with at least one hydrophobizing agent selected from the group consisting of a hydrophobizing agent containing an amino group, a silane coupling agent and silicone oil, and having a number average particle diameter of from 5 nm to 30 nm; wherein the external additive B is silicone resin particles having a ratio (BS/TS) of a BET specific surface area (BS), which is measured by a gas adsorption method, to a theoretical specific surface area (TS), which is obtained by calculating from a number average particle diameter measured by scanning electron microscope (SEM) observation on a theoretical calculation formula, in a range of from 3.0 to 30.0, and having a number average particle diameter of from 0.05 \u03bcm to 1.00 \u03bcm; and wherein, with respect to 100 parts by mass of the colored resin particles, a content of the external additive A is from 0.1 part by mass to 2.0 parts by mass, and a content of the external additive B is from 0.1 part by mass to 1.0 part by mass.
