Abstract
An electrostatic charge image development toner satisfies the following: (ln η(T1)−ln η(T2))/(T1−T2) is −0.14 or less, (ln η(T2)−ln η(T3))/(T2−T3) is −0.15 or more, and (ln η(T2)−ln η(T3))/(T2−T3) is more than (ln η(T1)−ln η(T2))/(T1−T2), where η(T1) represents a viscosity η of the toner at T1=60° C., η(T2) represents a viscosity η of the toner at T2=90° C., and η(T3) represents a viscosity η of the toner at T3=130° C.
