Abstract

PURPOSE:To obtain the negative-chargeability capsule toners of stable polarity and a long life by containing kaolin or calcium carbonate. CONSTITUTION:About 5-20pts.wt. (preferably 7-13pts.wt.) of kaolin or calcium carbonate is contained in total 100pts.wt. of the core material for the toners and the resin component used for shells (It is preferable to compound in shells). Namely, the core material powder composed of pressure-fixable components such as natural wax and polyolefin is dispersed into the organic solvent solution (dispersion) of kaolin (or calcium carbonate) and insulating materials to be made into shells (such as styrene-base resins, acrylic-base resins, epoxy resins) and the resultant dispersion is spray dried, whereby the pressure-fixing capsule toners are obtained.
