<p>PROBLEM TO BE SOLVED: To provide a toner for a dry development method having various kinds of performances such as excellent fixing property, offset resistance, fluidity, durability, heat-resistant storage property with which fixed images with superior quality can be obtained. SOLUTION: The toner features that the surface roughness of the fixed image is <=3μm, or that the melting energy of the toner in the temperature range of <=60 deg.C is <=3 mJ/mg. Or, the above toner has >=45 deg.C glass transition temperature (Tg). Or, the toner shows two or more maxima in the mol.wt. distribution and <=1,200,000 difference in the mol.wt. between the maxima.</p> |
