摘要：
This binder for toner preparation comprises as the main constituent thereof a polyester (X) composed of a polybasic acid component and a polyhydric alcohol component with a rosin-modified polyhydric alcohol (ab) introduced as part of the polyhydric alcohol component. The rosin-modified polyhydric alcohol is prepared in advance by reacting a polyhydric alcohol (a) having three or more hydroxyl groups with a rosin type compound (b).
