Abstract: PURPOSE:To obtain a toner having a desirable grain size distribution at a good yield by discharging an aq. medium and polymerizable monomer compsn. under a specific pressure difference while whirling the medium and compsn. so as to generate vortex shearing flow. CONSTITUTION:A coloring agent, such as carbon black, a charge control agent, wax and others, such as toner characteristic improving agent, at need are added into the polymerizable monomer and these materials are uniformly mixed and dispersed by a wet process medium type grinding mill, such as attriter. A polymn. initiator is added to the polymerizable monomer compsn. obtd. in such a manner to form an oil phase and the oil phase is whirled under pressurization in the aq. medium in the presence of a dispersion stabilizer. The shearing force by the vortex flow is utilized. Namely, a continuous type dispersing machine utilizing the vortex flow or the vortex flow and cavitation is used under 30 to 200kg/cm G pressurization. The improvement in the grain size distribution of the toner is made and the small-grain size toner having a sharp grain size distribution to be desired for upgrading of image quality is obtd. at a good yield.

Abstract: PURPOSE:To obviate defective cleaning and to obtain a toner which forms sharp images without deteriorating image quality even at the time of continuous copying of multiple sheets by incorporating an aliphat. acid metal salt into a polymerizable monomer and polymerizing the monomer. CONSTITUTION:This toner is obtd. by adding the metal salt of the fatty acid, more particularly the aluminum salt of the higher fatty acid to the polymerizable monomer with and into which a coloring agent, electrostatic charge control agent and other necessary toner characteristic improving agents are mixed and dispersed, then subjecting such monomer to suspension polymn. Since the toner obtd. in such a manner has itself the excellent cleanability, the cleaning defect which is heretofore not completely prevented by an ordinary method of adding a cleaning assistant externally into the toner or developer is prevented and the possibility of filming of the cleaning agent itself on a photosensitive body and accumulation thereof into the developer is eliminated. The excellent cleanability is thereby obtd. and the sharp images are always obtd. without deteriorating the image quality even at the time of continuous copying of many sheets.

CONSTITUTION:This heat pressure-fixing capsule toner is constituted of a heat- melting core material containing at least a thermoplastic resin and a colorant and an outer shell provided to cover the surface of the core material. A polymerization composition containing a polymerizable monomer, a colorant, a compound expressed by the formula, and a hydrophilic outer shell material is suspended in a dispersion medium and polymerized to form the core material and the outer shell. In the formula, M indicates Fe or Cr; X, Y , Y independently indicate the ArNHCO group or H, Cl, Br, NO2; Z indicates H, Na, K, NH4, NR4; Ar indicates phenyl group in which an alkyl group having the carbon number of 1-4 is substituted or the unsubstituted phenyl group; and R indicates an alkyl group having the carbon number of 1-4.

Abstract: PURPOSE:To produce the toner which sharpens a grain size distribution and can reform the quality of a toner surface by mixing the suspension of toner precursor particles contg. a polymer and the emulsion soln. of a polymerizable monomer compsn. CONSTITUTION:The method for obtaining the electrostatic charge image developing toner by a suspension polymn. method is constituted of a stage (A) for preparing the suspension of the toner precursor particles contg. the polymer, a stage (B) for mixing the suspension of the toner precursor particles and the emulsion soln. of the polymerizable monomer compsn. contg. at least a separately prepd. polymerizable monomer, emulsifier and water and a stage (C) for polymerizing the toner precursor particles swollen by the polymerizable monomer compsn.
