Abstract
The present invention provides a toner which can properly ensure elasticity and viscosity after transiting fixing nip, can improve surface smoothness of the fixing surface, fixing strength of a toner and transparency, low temperature fixing ability, and can prevent fattening of characters by using dynamic viscoelastic characteristics more conformable for actual toner behavior in fixation by heating, further provides an image-forming apparatus capable of forming a high quality image while enhancing low temperature fixing ability, realizing oil-less fixation and preventing offset of a toner.
