[PROBLEMS] To maintain excellent releasability in oil-less fixing, maintain a state without a roll contact mark when discharging a fixed image for a long period of time, and fixing characteristics such as excellent fixed image surface glossiness and OHP transparency. Providing toner for electrostatic charge development satisfying excellent fine image quality. Storage viscoelasticity at 120 ° C. (G) when a dynamic viscoelasticity measurement is performed by a sinusoidal vibration method at a measurement frequency of 6.28 rad / s, including at least a binder resin, a coloring material, and a release agent. '120) and storage viscoelasticity (G'180) ratio at 180 ° C (G'120 / G'180) is 14 to 150, and the release agent is polyalkylene. Toner for developing electrostatic latent image.
