<p>PROBLEM TO BE SOLVED: To provide a toner excellent in low-temp. fixability and durability, having a large quantity of electric charges and a narrow distribution of quantity of electric charges, ensuring rapid kickoff of electrostatic charge and excellent in chargeability. SOLUTION: A resin mixture of a resin having nitrile groups as a high molecular component with a resin such as a resin having nitrile groups, polyester resin, styrene-acrylic resin, polyurethane resin, epoxy resin or polyamide as a low molecular component is used as a toner binder and a polymer consisting of monomeric units each having a quat. ammonium salt group is used as an electric charge controlling agent.</p> |
