Toner

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 —R 1 OH, —R 1 COOH,

 and —R 1 NH 2 wherein R 1 represents a single bond or a C 1-4 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.

2. The toner according to claim 1 , which has a glass transition temperature in the second heating-up step of 45 to 60° C.

3. The toner according to claim 1 , which has a crystalline polyester content of 2.0 to 12.0 mass parts per 100 mass parts of the binder resin.

4. The toner according to claim 1 , wherein the polyester having the structure represented by formula (1) comprises 0.5 to 5.0 mass % of the structure represented by formula (2)

5. The toner according to claim 1 , wherein each of the Rs is the methyl group.

6. The toner according to claim 1 , wherein the crystalline polyester is a polycondensate of an aliphatic diol having 6 to 18 carbons with an aliphatic dicarboxylic acid compound having 6 to 18 carbons.
