(57) Abstract: A binder resin composition for non-contact fixing, which effectively prevents generation of voids in non-contact fixing and has not only excellent fixing properties but also excellent environmental resistance and storage stability. A non-contact fixing toner containing the binder resin composition for non-contact fixing; and a developer containing the non-contact fixing toner. A non-contact fixing resin composition comprising two or more polyesters having different softening points, wherein each of the polyesters has substantially the formula (I): Wherein R is an alkylene group having 2 or 3 carbon atoms, x and y Is a positive number, and the sum of x and y is from 1 to 16) is a resin obtained by using only a compound represented by the formula (1) as an alcohol component, and at least the polyester having the highest softening point is a crosslinked polyester. A non-contact fixing binder resin composition, a non-contact fixing toner containing the non-contact fixing resin composition, and a developer containing the non-contact fixing toner. |
