<p>PURPOSE: To enhance resistance to environmental pollution and durability and to obtain a sharp image free from fog and superior in transparency by obtaining a toner by dying with a diaminoanthraquinone-based compound in which a cyano or alkoxycarbonyl group is substituted. CONSTITUTION: This toner is dyed with a diaminoanthraquinone-based compound in which cyano or alkoxycarbonyl group is substituted, and the amino group may have a substitution group. This compound can be embodied by a compound represented by the formula in which R is H atom or an alkyl or cycloalkyl or allyl or phenyl group each optionally substituted and this R can be embodied by a 1-8C straight or branched alkyl group, and the substituted alkyl group can be embodied by a 2-hydroxyethyl group and the like, and X is a cyano or alkoxycarbonyl group.</p> |
