<p>PURPOSE:To provide the high-quality toner which hardly generates staining of copies, etc., regardless of the lapse of time by incorporating cyclooligosaccharides or their derivatives into the toner. CONSTITUTION:This electrostatic charge image developing toner contains >=1 kinds of the cyclooligosaccharides or their derivatives. A the cyclooligosaccharide cycloinurooligosaccharide consisting of fructose or cyclodextrin consisting of glucose or its deriv. are particularly preferable and they are the compd. expressed by formula I or formula II. In the formulas I, II, R<1> to R<6> respectively denote hydrogen atom, an alkyl group, acyl group, etc,; all of R<1> to R<6> may be the same as or different from each other; (n) and (m) denote any number from 6 to 8; R<1>, R<4> denote hydrogen atom; R<2>, R<3>, R<5>, R<6> are preferably a methyl group; (n) and (m) are preferably 6.</p> |
