ABSTRACT:
A toner binder is disclosed which comprises a polyester resin in which an aliphatic hydrocarbon chain terminated with an ester and/or an ether bond to the aliphatic group contains a constituent element consisting of ethylene in an amount of from 1 to 5 wt % based on the total weight of the resin. Further disclosed is a toner binder using both of a crosslinked polyester having a peak molecular weight of 10,000 or less and a linear polyester having a peak molecular weight of 8,000 or more as binder resins, the peak molecular weight of the linear polyester being greater than the peak molecular weight of the crosslinked polyester.
