MEMBER FOR IMPARTING TRIBOELECTRIC CHARGE FOR POSITIVELY CHARGEABLE TONER

PURPOSE:To obtain a bright color picture exhibiting a quality equivalent to the initial picture even after continuous copying, without any change in positive charge amt. and which is hardly altered by the environment by incorporating a compd. selected from a group of specified compds. into the surface as a charge control agent. CONSTITUTION:One or >=2 kinds of compds. selected from a group of compds. expressed by formula I or II is incorporated into the surface as a charge control agent. In formulas I and II, A and B are independently hydrogen atom, halogen atom, etc., R is hydrogen atom, alkyls capable of having a substituent, etc., (m) is an integer of 2 to 16, and (n) is an integer of 4 to 8. As a result, a toner can be applied to a carrier, a conveyor member such as developing sleeves, doctor blade and other triboelectric charge imparting member, a sufficient mechanical strength is imparted to the members, a triboelectric charge is imparted to the conveyor members and triboelectric charge imparting member, the members are not deteriorated in performance even after long-period continuous use, and excellent positive chargeability is imparted to the toner.
