<p>PURPOSE: To obtain a toner fixable at a low fixing temp., not causing any problem on anti-offsetting property and shelf stability in practical use and excellent in fixing strength to transfer paper by incorporating Fischer-Tropsch wax derived from natural gas. CONSTITUTION: This electrophotographic toner contains Fischer-Tropsch wax derived from natural gas. The wax is produced by the Fischer-Tropsch's process using natural gas as starting material and it is wax hydrocarbon synthesized by the catalytic hydrogenation of CO. The wax is structurally straight chain paraffin wax with few methyl branches. Since the wax has a lower m.p. than PP wax, it is excellent in low-temp. fixability and excellent also in shelf stability. Because of a low penetration of <=2, the wax does not deteriorate the flowability of a toner when incorporated into the toner and it does not cause any problem on triboelectric chargeability, etc.</p> |
