Abstract
A toner for developing electrostatic images contains a binder resin, a colorant, a release agent, and a charge control agent. The release agent contains a wax having a polar group. The toner for developing electrostatic images has tan δ of 1 to 2 at a temperature of 80° C. to 145° C. as measured with a viscoelasticity measuring apparatus at a frequency of 10 Hz and a shear stress of 500 Pa, and has a breaking point of 180° C. or less in a temperature-tan δ curve.
