    摘要： The invention provides a fine powder production apparatus comprising a pneumatic classifying means and a pneumatic impact pulverizing means, wherein said pneumatic impact pulverizer has an accelerating tube for accelerating powder to be pulverized with high pressure gas, and a pulverizing chamber which is equipped with an impact member against which powder collides to pulverize. One end of the acceleration tube is provided with a powder feed port and a high pressure gas ejection nozzle which are concentrically arranged. Further, a communicating means is provided for feeding discharged coarse powder from the pneumatic classifying means to the pneumatic impact pulverizing means. The pneumatic classifier means has a classifying chamber, a classifying plate having its center swelled, and a classifying louver so that powder fed with carrier gas is whirled in the classifying chamber and classified into fine powder and coarse powder by means of centrifugation.

    摘要： A microcapsule toner is produced through the steps of: passing resinous base particles (A1) comprising at least a binder resin and modifier particles (B) having a particle size ratio of 0.2 or less with respect to the base particles (A1) through an impact zone having a minimum clearance of 0.5 - 5 mm between a rotating member and a fixed member or between at least two rotating members at an ambient temperature of 10 - 90 C thereby to fix the modifier particles (B) onto the surfaces of the base particles (A1) under the action of a mechanical impact force to form particles (A2), the modifier particles (B) being particles selected from the group consisting of charge-controlling particles releasing particles, colored particles, charge-suppressing particles and abrasive particles; and passing the particles (A2) and shell-forming resin particles (C) having a particle size ratio of 0.2 or less with respect to the particles (A2) through an impact zone having a minimum clearance of 0.5 - 5 mm between a rotating member and a fixed member or between at least two rotating members at an ambient temperature of 10 - 90 °C thereby to fix the shell-forming resin particles onto the surfaces of the particles (A2) under the action of a mechanical impact force to form a shell, thus obtaining a microcapsule toner.

    摘要： A process for producing a toner for developing electrostatic images is disclosed. A polymerizable monomer composition is first prepared and dispersed in an aqueous medium by the action of high shear force to produce particles. The polymerizable monomer is then polymerized in a container having a jacket. The liquid temperature inside the container is controlled by feeding a high-pressure vapor into the jacket while adjusting the degree of vacuum inside the jacket. The production process can achieve a superior temperature response, can keep the reaction system at a constant temperature with ease and can realize shortened production time and reduced production cost.

    摘要： A toner for developing electrostatic latent images is produced by classifying feed toner particles supplied through a supply nozzle (16) into at least three fractions in a classifying chamber divided into at least three sections (11,12,13) and placed under a reduced pressure under the action of the inertia force of the toner particles supplied together with a gas stream and the centrifugal force of the curved gas stream due to Coanda effect. A first gas introduction pipe (14) and a second gas introduction pipe (15) are disposed above the classifying chamber so as to provide a first inlet and a second inlet opening with the first inlet being disposed closer to the supply nozzle than the second inlet. The magnitudes of the static pressures Pi and P 2 in the first and second gas introduction pipes are controlled so as to satisfy the relations of: |P 1 | ≧ 150 mm.aq., |P 2 | ≧ 40 mm.aq. and |P 1 | - |P 2 | ≧ 100 mm.aq.

    摘要： A process for producing a toner has the steps of, polymerizing a polymerizable monomer composition containing at least a polymerizable monomer and a colorant, in an aqueous dispersion medium to form colored polymer particles, and thereafter washing the colored polymer particles, followed by dewatering to prepare wet colored polymer particles, subjecting the resultant wet colored polymer particles to substantial removal of the water held by the wet colored polymer particles, by means of a dryer making use of hot air to obtain toner particles, and drying the toner particles under reduced pressure by means of a vacuum dryer so that polymerizable monomers remaining in the toner particles come to be in a residue of 200 ppm or less.
