PURPOSE:To enable formation of red, yellow, purple, and sepia colored sharp images free from fog and superior in light resistance by incorporating gamma-Fe2O3 and a binder resin and electrically conductive ZnO. CONSTITUTION:A toner contains gamma-Fe2O3 and a binder resin and electrically conductive ZnO in an amt. of 0.05-5wt% ZnO based on the toner. The magnetic toner of such a compsn. is good in electrostatic chargeability and transferability, and superior in durability. As a result, a sharp color image of red, yellow, purple, or sepia color type, and free from unevenness of transfer and fog can be obtained. |
