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 pneumatic pulverizer comprises an accelerating tube for carrying and accelerating powder to be pulverized with high-pressure gas and a pulverizing chamber for pulverizing the powder to be pulverized. The back end of the accelerating tube is provided with a pulverization powder feed port for feeding powder to be pulverized to the accelerating tube, the pulverizing chamber has an impact member having an impact surface opposed to the opening plane of the outlet of the accelerating tube, the and a side wall against which the powder to be pulverized that has been pulverized by the impact member collides to further pulverize. The closest distance from the side wall to a margin of the impact member, is shorter than the closest distance from the front wall of the pulverizing chamber opposed to the impact surface to the margin of the impact member, to prevent pulverized powder from fusing, coagulating, and getting coarser, and prevent localized abrasion of an impact surface the impact member and the accelerating tube.

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.degree.-90.degree. 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.degree.-90.degree. 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.
