Abstract:
The present invention provides a crystalline polyester resin having a sharp melt property that realizes both fixing performance and blocking property and demonstrates favorable charging performance, in which the crystalline polyester resin for toner, satisfying the following relationships, 25≦Tg≦70, and (Tg+273)/(Mp+273)≧0.75, wherein Tg (° C.) represents a glass transition temperature of the crystalline polyester resin for toner, and Mp (° C.) represents a melting point of the crystalline polyester resin for toner.
