Patent ID: 8703376

Claim:
A toner comprising: a binder resin, a releasing agent, and a colorant, wherein the binder resin comprises a polyester resin (A) and a polyester resin (B), wherein the polyester resin (A) is produced by polycondensing an alcohol component not containing an alkylene oxide adduct of bis-phenol A with a carboxylic acid component which contains a rosin compound in an amount of 5% by mass or more of the total amount by mass of the alcohol component and the carboxylic acid component, wherein the polyester resin (B) is produced by polycondensing an alcohol component containing an alkylene oxide adduct of bisphenol A represented by General Formula (1) given below and an aliphatic diol with a carboxylic acid component, and wherein the rosin compound includes abietic acid, the polyester resin (A) includes polycondensed units of abietic acid derived from the rosin compound, and the toner contains abietic acid derived from the rosin compound other than the polycondensed units of abietic acid in the polyester resin (A), and wherein the toner contains abietic acid in an amount of 0.01% by mass to 1% by mass based on the total mass of the toner: where R 1 and R 2 each represent a C2-C4 alkylene group; R 3 and R 4 are each any one of a hydrogen atom, a C1-C6 straight-chain alkyl group, and a C1-C6 branched-chain alkyl group; and x and y each represent a positive integer and the sum of x and y is 1 to 16.
