Abstract
A toner, including a binder; a colorant; and a wax including a molecular chain constituted of only a C—H bond and a C—C bond, and having a melting point of from 50 to 78° C. and a melt viscosity of from 5 to 15 mPa·S at 140° C., wherein the toner has a weight reduction rate of from 0.001 to 0.1% by weight/min when measured by TGA (Thermogarvimetric Analysis) method in an atmosphere at 165° C. for 10 min.
