Electrostatic image developing toner, production method thereof, electrostatic image developer and image-forming process

It is to easily form a fixed image, especially a full color image, that exhibits a small difference in gloss depending on the fixing conditions of the toner, is excellent in smoothness, exhibits small unevenness of gloss, and has high image quality and high reliability. A toner for developing a static image to be fixed by heat on a fixing substrate, wherein a fixed image has a gloss Gm of about 20% or more, and a maximum value of a degree of change Gs of the gloss per 1&deg; C. of a difference of a surface temperature within a range of about from 140 to 170&deg; C. of a fixing member as a heating and fixing unit is 1.8% or less per 1&deg; C.; and a developer for a static image and a process for producing an image using the toner are provided.

Toner for developing static image, developer for developing static image, and image forming method

An electrostatic-charged image developing toner containing a binder resin and a coloring agent, which is excellent in the fixing characteristics, has high charging uniformity and stability, and gives excellent images, wherein the crosslinking molecular weight Mc of the toner obtained by a temperature dispersion measurement in the dynamic viscoelasticity of the toner is from about 1.6.times.10.sup.4 to 3.5.times.10.sup.6, or the crosslinking density Me thereof is from about 1.6.times.10.sup.-8 to 3.5.times.10.sup.-6 /Kmol.
