Toner for development 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 include at least:
• silica fine particles A having a number average particle diameter of from 5 nm to 19 nm,
• silica fine particles B having a number average particle diameter of from 20 nm to 200 nm, and
• electroconductive metal oxide fine particles C having a number average particle diameter of from 0.05 to 1 μm;
• wherein the silica fine particles A and B are silica fine particles 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 a silicone oil;
• wherein the electroconductive metal oxide fine particles C have an electrical resistance of 70 Ωcm or less and contain antimony-doped tin oxide;
• and
• wherein, with respect to 100 parts by mass of the colored resin particles, a content of the silica fine particles A is from 0.1 to 2.0 parts by mass;
• a content of the silica fine particles B is from 0.1 to 3.0 parts by mass;
• and a content of the electroconductive metal oxide fine particles C is from 0.1 to 1.0 part by mass.
