Toner for developing electrostatic images

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,

• 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 20 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 μm to 1.00 μm;
• 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.
