TONER BINDER, AND TONER

The toner binder of the present invention contains a crystalline resin (A) and a resin (B) that is a polyester resin or its modified resin, the polyester resin being obtained by reaction of an alcoholcomponent (X) and a carboxylic acid component (Y) as raw materials, wherein a temperature (Tp) of the top of an endothermic peak derived from the crystalline resin (A) as measured by a differential scanning calorimeter (DSC) is in the range of 40 DEG C to 100 DEG C, and endothermic peak areas S1 and S2 during heating satisfy the following equation. S2/S1*100>= 35 (1) is an area of the endothermicpeak derived from the crystalline resin (A) in the first heating process, and S2 is an area of the endothermic peak derived from the crystalline resin (A) in the second heating process, when the toner binder is heated, cooled, and heated. 本发明涉及色调剂粘结剂和色调剂。本发明的色调剂粘结剂的特征在于，含有结晶性树脂(A)和树脂(B)，该树脂(B)是以醇成分(X)和羧酸成分(Y)作为原料进行反应而得到的聚酯树脂或其改性树脂，利用差示扫描量热计(DSC)测定的表示源自结晶性树脂(A)的吸热峰顶的温度(Tp)在40～100℃的范围，升温时的吸热峰面积S与S满足下述关系式(1)。(S/S)×100≥35 (1)
