Zusammenfassung:	PURPOSE: Provided are an amphipathic copolymer, which has excellent transfer efficiency with no need of any separate coloring agent and gives coloring particles having excellent color rendition, and an electrophotographic toner composition comprising the same. CONSTITUTION: The amphipathic copolymer comprises at least one S-part and at least one D-part, and has a chromophore bonded covalently through a urethane, urea or amide linkage. The chromophore is a single color chromophore or a plurality of chromophores having different colors. The electrophotographic toner composition comprises: (a) a liquid carrier having a Kauri butanol value of less than 30 ml; and (b) a plurality of toner particles dispersed in the liquid carrier, wherein the toner particles comprise a polymeric binder comprising the amphipathic copolymer as defined above.
