PURPOSE:To improve magnetic characteristics and to facilitate the formation of bright color images by forming a magnetic material of a high-polymer metal complex formed by introducing two porphyrins contg. a metal having respectively specific numbers of electrons in a (d) orbit via an ester group to a polymer main chain. CONSTITUTION:The magnetic material is formed of the inorg. magnetic material consisting of the high-polymer metal complex formed by introducing the porphyrins contg. the metal having one electron in the (d) orbit and the porphyrins having 9 electrons in the (d) orbit via the ester group to the polymer main chain. The toner compounded with the high-polymer metal complex is still lower in magnetic force than the toner compounded with the inorg. magnetic material. The sufficient magnetic force as the magnetic toner is, therefore, assured by the inorg. magnetic material if the magnetic material of the high-polymer metal complex system and the inorg. magnetic material are used in combination as the magnetic material. In addition, the reduction in weight is attained by the magnetic material consisting of the high- polymer metal compex without impairing the magnetic force. The sufficient magnetic force as the magnetic toner is assured in this way and the color images which can brightly produce the colors of coloring materials are obtd. |
