Abstract

PURPOSE:To produce the capsule toner which is good in pressure fixability, is superior in chargeability, has impact resistance and is long in life by covering the core material containing pressure-fixable resins with the shells containing cyclized rubber and insulation type resins. CONSTITUTION:Core material containing resins which are liable to intertwine with the fibers of plain paper under pressure of linear pressure about 20kg/cm, particularly polyethylene oxide, is covered with the shells of 0.8 to 2mum thick mixed with 85 to 50wt% of cyclized rubber preferably of natural rubber as its raw material and 15 to 50wt% of styrene-butadiene copolymer. It is equally well even if a suitable amount of charge control agents be added in the shells. If necessary, coloring agents are added in the core material or shells. Further, when magnetic fine particles are contained in the core material, the magnetic toner for one-component base developer which is good in developability and pressure fixability and is capable of performing electrostatical transfer may be obtained.
