Patent ID: 7300736

Claim:
A toner comprising: (A) a binder resin; (B) a colorant; (C) a charge controlling agent; and (D) an additive; wherein said binder resin (A) comprises: a polyester resin containing no tetrahydrofuran-insoluble component; and having a molecular weight distribution wherein components having a molecular weight not greater than 5×10 2 are present in an amount of 4% or less by weight, and wherein a main peak is present in a molecular weight range of from 3×10 3 to 9×10 3 when the molecular weight distribution is determined by gel permeation chromatography; wherein said charge controlling agent (C) comprises: a metal salt of salicylic acid or salicylic acid derivative; and wherein said additive (D) comprises: a hydrophobized silica having a primary particle diameter of from 0.01 to 0.03 μm; and a hydrophobized titanium oxide having a primary particle diameter of from 0.01 to 0.03 μm and a specific surface area of from 60 to 140 m 2 /g, wherein the hydrophobized titanium oxide is prepared by surface-treating a particulate titanium oxide prepared by a wet process, wherein said hydrophobized titanium dioxide comprises one or more water-soluble components in an amount of 0.2% or more by weight, and has a transmittance not less than 35% for light having a wavelength of 300 nm and a transmittance not less than 80% for light having a wavelength of 600 nm.
