Abstract

PURPOSE:To increase toners fluidity remarkably and to improve custody and supply of toners or its movement on a supporting carrier, by preparing toners for electrostatic recording by containing polyphosphagen having a specific substitution into a developer. CONSTITUTION:Polyphosphagen expressed in the formulaI(R and R' show alkyl groups fluorine substd. respectively, preferably alkyl groups fluorine substd. having 2-6 carbon numbers and n shows >=1 at least, preferably 200-20,000 integral number) is contained into a developer to prepare toners for electrostatic recording. The above-mentioned polyphosphagen is formed of polyphosphagen film by spraying solvent solution of polyphosphagen to the surface of toner particles e.g. after forming the particles. A preferable adding amount of polyphosphagen is 2-30% to a total resin component.
