<p>PURPOSE:To make restoration velocity of triboelectric charge quantity fast and to make triboelectric charge property always stable independent of the number of copying when the toner is left standing under high humidity by incorporating a specified boron compd. CONSTITUTION:This toner is incorporated with at least one kind of compds. expressed by formula I and II. In the formula, R<1> and R<2> are each hydrogen and halogen atom, alkyl, alkoxy, acyland ester group, R<3> is halogen atom, alkyl, alkoxy, acyl and ester group. Moreover, R<1>-R<3> may be substituted for aryl group. Z<+> is cation. There is no limitation for the cation in the formula I and II, but, for example, an inorg. cation such as proton and metallic ion and an org. cation such as ammonium ion, phosphonium ion and piridinium ion are exemplified.</p> |
