Abstract
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 alcohol component (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° C. to 100° C., and endothermic peak areas S1 and S2 during heating satisfy the following equation. (S2/S1)×100≥35 (1) S1 is an area of the endothermic peak 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.
