TRIBOELECTRIC CHARGE IMPARTING MEMBER FOR NEGATIVE CHARGE TYPE TONER

PURPOSE:To obtain a member applicable to a carrier, a transfer member or other triboelectric charge imparting member having mechanically satisfactory strength, ensuring triboelectric charge imparting property, not deteriorating the performance even after continuous use over a long period of time and capable. of imparting superior negative chargeability to a toner by incorporating a specified compd. into the surface of a member. CONSTITUTION:This triboelectric charge imparting member contains one or more kinds of compds. represented by formula I in at least the surface. In the formula I, X is a group represented by formula II, III or IV and Y is H, alkyl or aryl. In the formulae II-IV, A is an electron withdrawing group, each of R1 and R2 is H, halogen, alkyl, cycloalkyl, alkoxyl, aryl, aralkyl or hydroxyl, R1 and R2 may form a ring and the electron withdrawing group is, e.g. F, Cl, Br, I or halogen substd. alkyl such as trifluoromethyl.
