摘要： A toner prepared by allowing finely-divided particles of a vinyl resin having an alkali-reactive group to react with a fluorine-containing quaternary ammonium salt to obtain surface-modified finely-divided particles; mixing the surface-modified finely-divided particles and core particles composed of a resin and a coloring agent; and filming the above core particles with the finely-divided particles of the surface-modified vinyl resin with application of mechanical energy thereto.

摘要： A developer apparatus for a printing device includes a rotatable developer carrying member which carries developer thereon. A magnet assembly is disposed in the developer carrying member. The magnet assembly includes a plurality of magnets for conveying the developer. The magnets generate a magnetic field over a larger proportion of a circumference of the developer carrying member in an edge region adjacent an end of the developer carrying member than in a mid-region longitudinally spaced from the end of the member by the edge region. The apparatus enables unwanted toner emissions to be reduced by the development of a stable annular magnetic brush in the edge regions.

摘要： A process for improving the electrostatic charge developed on a resin powder composition for electrostatic coating of solid objects and the method of application thereof. The resin powder comprises (i) a thermosetting or thermoplastic resin and (ii) an electrostatic property modifying agent (polyalkylene ether, polyalkylene glycol, polyethoxylated stearyl alcohol) incorporated in the resin or on the surface of the resin. The methods of application of the powder involves charging the powder by electrical induction/conduction and spraying the charged powder onto a grounded solid object to which it adheres prior to the thermal fusing to produce a permanent finish.

摘要： An apparatus for improving the electrostatic charge developed on a resin powder composition for electrostatic coating of solid objects and the method of application thereof. The apparatus comprises a device for charging the powder by electrical induction/conduction such that the powder particles have a resistivity of from about 10.sup.9 to about 10.sup.13 ohm.meters at 20 percent relative humidity and spraying the charged powder onto an grounded solid object to which it adheres prior to the thermal fusing to produce a permanent finish.
