Abstract
Provided is a toner binder which attains all of low-temperature fixing properties, gloss, and hot offset resistance and gives a toner that satisfies the flowability, high-temperature storability, charge stability, pulverizability, image strength, flex cracking resistance, and document anti-offset properties. The present invention is a toner binder which comprises a polyester resins and has a surfactant content of 100 ppm or less and in which the THF-insoluble components and the THF-soluble components respectively have a storage modulus (Pa) at 150° C., G', and the storage modulus (Pa) at 150° C., G′, which satisfy the following relationships (1) and (2).≥10,000  (1)≥500  (2)
