Abstract:
A toner according to an embodiment includes a colorant, a binder resin, and an ester wax. The colorant, the binder resin and the ester wax form a toner particle. The ester wax contains two or more ester compounds represented by the general formula R1COOR2, where R1 and R2 each independently is an alkyl group. The total number of carbon atoms of R1 and R2 is in a range from 31 to 53. The two or more ester compounds have different number of carbon atoms from each other.
