Toner

A toner comprising colored resin particles containing a binder resin, a colorant, a softening agent and a charge control agent, and an external additive,

• wherein fatty acid metal salt particles are contained as the external additive;
• wherein a glass transition temperature (Tg) specified from a temperature dependence curve for a loss tangent (tan δ) of the toner, which is obtained by a dynamic viscoelastic measurement of the toner at a measurement frequency of 24 Hz, satisfies 65.0° C.≤Tg (° C.)≤75.0° C.;
• wherein, in the temperature dependence curve for the loss tangent (tan δ) where tan δ (Tg) is a loss tangent (tan δ) at Tg and tan δ (100° C.) is a loss tangent (tan δ) at 100° C., an area of a trapezoid where the upper base, lower base and height are a value of tan δ (100° C.), a value of tan δ (Tg) and a value of 100−Tg, respectively, is 35.0 or more and 48.0 or less;
• and
• wherein a ratio of a blow-off charge amount of the toner after a stirring time of 1800 seconds to a blow-off charge amount of the toner after a stirring time of 180 seconds, both of which are measured by the following charge amount measurement method, is 0.50 or more and 1.00 or less:
• [charge amount measurement method]
• first, 0.25 g of the toner and 9.75 g of a spherical, non-coated Mn—Mg—Sr—Fe type ferrite carrier having an average particle diameter of 60 μm, are put in a glass container having a volume of 30 cc (inner bottom diameter 30 mm, height 50 mm);
• in an environment at 23° C. and a relative humidity of 50%, a triboelectric charging treatment is carried out by stirring them by use of a roller mixer at a rotation of 160 rpm for a predetermined time;
• 0.2 g of a mixture of the toner and ferrite carrier after the triboelectric charging treatment, is put in a Faraday cage;
• and by use of a blow-off powder charge amount measuring device, the toner is blown off for 30 seconds in a condition of a nitrogen gas pressure of 0.098 MPa, and the blow-off charge amount (μC/g) of the toner is measured.
