<p>PROBLEM TO BE SOLVED: To provide a dry toner fixable at a low temperature and high in anti-offset property at high temperature, and high in image density, small in fog on a fixed image, and superior in blocking resistance, and prevented from melt attaching of the toner to a photoreceptor and winding of an image fixed sheet around a fixing roller. SOLUTION: This dry toner contains e binder resin having carboxylic acid or acid anhydride groups and contains an oxazoline derivative compound having >=2 oxazoline groups in the molecule in an amount of 0.001-30 weight% of the binder resin or a resin component having >=2 oxazoline groups in an amount of 0.01-50 weight% in the binder resin, and in the viscoelastic characteristics of the toner it has a storage elasticity G'75 at 75 deg.C of 3×105-3×107 Pa and that G'125 at 125 deg.C of 1×103-1×105 Pa, and that G'195 at 195 deg.C of 2×102-4×104 Pa.</p> |
