Patent ID: 8288499

Claim:
A polyester for a toner having a softening point of from 70Â° C. to 110Â° C. and a glass transition temperature of from 38Â° C. to 60Â° C., obtained by polycondensing an alcohol component comprising a propylene oxide adduct of bisphenol A and an ethylene oxide adduct of bisphenol A in a total amount of 95% by mole or more, with a carboxylic acid component, wherein the propylene oxide adduct of bisphenol A has an average number of moles of from 2.0 to 2.4, and the ethylene oxide adduct of bisphenol A has an average number of moles of from 3.1 to 3.5, a ratio of the average number of moles of the propylene oxide adduct of bisphenol A (a) and the average number of moles of the ethylene oxide adduct of bisphenol A (b), b/a, is from 1.1 to 1.4, and a mole ratio of the propylene oxide adduct to the ethylene oxide adduct in the alcohol component is from 5/95 to 30/70.
