A toner is provided which is superior in the long-term storage stability and has high low-temperature fixing properties. In a DSC curve as measured with a differential scanning calorimeter, the toner has a glass transition temperature of not less than 50 DEG C and not more than 60 DEG C; and the toner has, in regard to a resin composition contained therein, a difference of not less than 0.060 W/g in heat flow between a point on the curve at a temperature of 40 DEG C and a baseline in the range exceeding the glass transition temperature; and in viscoelastic characteristics measured at a frequency of 6.28 rad/sec, the toner has a storage elastic modulus (G'40) at a temperature of 40 DEG C of not less than 7.0 x 108 Pa and not more than 2.0 x 109 Pa, and a storage elastic modulus (G'70) at a temperature of 70 DEG C of not less than 1.0 x 105 Pa and not more than 1.0 x 107 Pa.
