New electrostatographic developers are provided, containing dual function polymeric binder/charge agents. The new developers contain toner particles comprising a vinyl addition binder polymer containing a quaternary phosphonium salt, wherein the phosphonium salt has a cationic portion comprising a phosphorus atom covalently bonded to the binder polymer.
