摘要： An apparatus for forming a cloud of magnetic toner particles has a rotatable magnet roller with a number of magnetic poles disposed within a non-magnetic cylindrical sleeve. Magnetic toner particles are supplied from a hopper onto the sleeve. A magnetic bar is disposed above the sleeve. The rotation of the magnet roller causes the sleeve to carry magnetic toner particles thereon. When the magnetic toner particles carried approach to the magnetic bar, those become in a cloudy state.

摘要： This invention is concerned with a method for forming spherical particles of thermoplastic material, characterized by the step of blowing a stream of gas having thermoplastic particles dispersed therein from a peripheral region into a jet of pressurized hot gas to form the thermoplastic particles into uniform spherical particles. It also provides apparatus for carrying out the foregoing method which includes means for discharging a jet of pressurized hot gas from an outlet port and means for ejecting a stream of gas having thermoplastic particles dispersed therein from the periphery of the outlet port toward the jet of pressurized hot gas.

摘要： Toner for electrostatic image development, comprising a toner body powder which contains a thermoplastic resin binder having a first reactive functional group and a micro powder which has a second reactive functional group capable of a curing reaction with the first reactive functional group. Owing to the curing reaction between the first and second reactive functional groups, the micro powder particles are bonded on the particles of the toner body powder. Thus the toner is powder particles with non-adhesive surfaces and possesses a good preservation stability. Over a long time after its manufacture the toner can provide clear developed images.
