<p>PURPOSE:To obtain a toner which is excellent in the electrostatic charge characteristic by the friction even under a various environmental conditions and always gives a stabilized high-quality image by incorporating a specific compound. CONSTITUTION:The compound represented by formula I is incorporated. In the formula I, X and Y independently represents hydrogen atoms, formula II, etc., respectively. Where, X and Y are not hydrogen simultaneously and Z represents the hydrogen atom or an aryl group. Further, in the formula II, D1 and D2 independently represent the hydrogen atoms or an electron donating groups, respectively. Where, D1 and D2 are hot hydrogen simultaneously and R1 represents the hydrogen atoms, alkyl groups, cycloalkyl groups, aralkyl groups, aryl groups, halogen atoms, acyl groups, nitro groups, cyano groups or R2SO2-(R2 represents hydroxyl groups, amino groups, alkyl substitutional amino groups, alkyl groups, cycloalkyl groups, aralkyl groups, aryl groups or alkoxy groups). As a result, the stability of a compound and the diffusivity to a binder resin are satisfactory, thus the image excellent in fogging and splashing of the toner is obtained.</p> |
