Patent ID: 8735034

Claim:
A toner for electrostatic image development comprising toner matrix particles comprising at least a resin binder and a colorant, and an external additive, the external additive comprising composite oxide particles (an external additive A) that comprise titania and silica, wherein the external additive A comprises a core-shell structure in which a core portion comprises the titania and a shell portion comprises the silica, wherein the titania is present in the external additive A in an amount of from 75 to 95% by weight, the resin binder comprising a polyester obtained by polycondensing a carboxylic acid component comprising at least 55% by mol of an isophthalic acid compound, and an alcohol component (a polyester A), the colorant is a carbon black, which is present in an amount of from 3 to 15 parts by weight, based on 100 parts by weight of the resin binder, and a product of the amount in parts by weight of the external additive A contained based on 100 parts by weight of the resin binder and the amount in parts by weight of the carbon black contained based on 100 parts by weight of the resin binder is from 1 to 10.
