Toner for the development of electrostatic image, process for the preparation thereof, electrostatic image developer, and process for the formation of image

摘要

There is provided a toner for the development of an electrostatic image having a complex viscosity eta* of from 3.0x102 to 1.2x103 Pas at 160° C. and a loss tangent tan delta of from 0.60 to 1.60 as determined by temperature dispersion measurement method by sinusoidal oscillation method, a method for manufacturing the toner by a coaggregation fusion composite method, developer, and an image forming method.
