<p>PROBLEM TO BE SOLVED: To provide a polyester-based full-color toner having sharp melt property, fixing property, color developing property, blocking resistance and excellent durability without melt sticking to be used for an electrophotographic printing method, electrostatic printing method, etc. SOLUTION: This toner consists of (a)>=90 mol.% bivalent carboxylic acid component to the whole acid component and (b)>=90 mol.% aliphatic diol component to the whole acid component. The toner contains a polyester resin having >=5000 weight average mol.wt. Mw, >=1.8 ratio of Mw/Mn in the mol.wt. distribution, 50 to 70 deg.C glass transition temp., 95 to 150 deg.C softening temp., and <=15 mgKOH/g acid value.</p> |
