PURPOSE:To obtain the color toner which has a stable brown color and is inexpensive by compounding a compd. having phenyl propane skeleton. CONSTITUTION:The compd. having the phenyl propane skeleton, for example, lignin, is used as a coloring agent. The brown color of a natural color tone is stably and inexpensively obtd. in this way and the electrostatic chargeability is hardly affected by an environmental change. In addition, the toner which is a pale color up to the time before fixing and changes to an adequate brown color by heat after fixing is obtd. according to the kinds of the lignin. An intra-machine contamination is inconspicuous. Further, the lignin is a wood component and is harmless to the human body. |
