The color toner has capsule type toner particles each having a surface layer (B) mainly formed of a resin (b) on the surface of a toner base particle (A) containing at least a binder resin (a), a colorant, and a wax, in which (1) a temperature Tp at which a curve 1 obtained by plotting a temperature on an axis of abscissa and the common logarithm of a value obtained by dividing the loss modulus G'' of the color toner by the unit of the loss modulus on an axis of ordinate shows a maximum is present, and Tp satisfies the relationship of 40° C.<=Tp<=60° C., (2) a temperature Ts at which a curve 2 obtained by differentiating the curve 1 with respect to the temperature twice shows a local minimum is present in the temperature range of Tp+10(° C.) to Tp+40(° C.), and (3) a ratio G''(Ts)/G''(Ts+5) in the curve 1 is larger than 3.0.
