PURPOSE:To provide such a charge donating member that the performance does not deteriorate even for long-term use, the amt. of triboelectric charges of an electrostatic charge image developing toner is improved by using the charge donating member, and sharp picture images with good image density, reproducibility of fine lines and gradation with little fog can be obtd. CONSTITUTION:This charge donating member for electrostatic charge image developing has a compd. expressed by general formula (I) or 12 (II) on at least one part of its surface. In formula I, Ar<1> and Ar<2> are hydrogen atoms, alkyl groups which may have substituents, or aralkyl groups which may have substituents, X<n-> is a cation, and n is a natural number. In formula II, Ar<3> is a hydrogen atom, alkyl group which may have substituents, or aralkyl group which may have substituents, Y<m-> is cation, and m is natural number. |
