1. A toner, comprising:
a toner particle comprising a binder resin and a crystalline polyester, the binder resin comprising a polyester having a structure represented by formula (1)
where Rs independently represent hydrogen, a methyl group or a phenyl group;
A represents a polyester segment;
B represents a polyester segment or is selected from the group consisting of —R1OH, —R1COOH,
and —R1NH2 wherein R1 represents a single bond or a C1-4 alkylene group; and
average repeat number n is 10 to 80, wherein
ΔH1 is 1.0 to 10.0 J/g and (ΔH2/ΔH1) is 0.50 to 1.00 when ΔH1 is the endothermic quantity originating with the crystalline polyester in a first heating-up step measured on the toner by differential scanning calorimetry, and ΔH2 is the endothermic quantity originating with the crystalline polyester in a second heating-up step measured on the toner by differential scanning calorimetry.
