- Dispersion of miscible monomer A solution in which 3 parts of water-soluble (trade name: 8622 bis (2-meth (2-ide) pionad)) was dissolved was added to the reaction. After continuing the further 4 reactions, the reaction was stopped, and the dispersion of the A-shaped particles was obtained.
- the client was gradually added with trade name C. ⁇ Gumen 22) to produce a charged product. This,,, and initial is wide, and the gap is widened to the end, and it is widened to 3 at the end, and organic (meth)
- Methano 4 () was added according to the charged state. The part was taken out and dissolved by adding ton to make the charged 5 ton. 3 gaps on glass This solution was applied, dried and prepared using a doctor.
- a polymerizable monomer consisting of 8 parts, 2 parts of reactant, 6 parts of senzen and 25 parts of Pometexteno (manufactured by Kogyo Co., Ltd., trade names A6, 94C), 2 parts of the above,
- the mecaptan portion and the stay portion obtained in the above were dispersed in the chamber and in a bath to obtain an compatible monomer.
- methylmethacrylate 2 and 65 parts of water were finely dispersed by an ultrasonic machine to obtain a dispersion of a compatible monomer.
- oxixate (trade name) was added thereto until the mixture became stable.
- the dispersion obtained in this way was passed through a rider (produced by Hara Seisakusho Co., Ltd., trade name 33) rotating at 5 in 3 seconds, passed through the dispersion, passed through the inner nose, and returned to the original stirring. The jet velocity was returned to 5 and a monomer was formed.
- the inner nose was adjusted so that the end was located at a position 5 below the surface of the nose, and formed by turns. A cooling jacket was attached around the rider, and a 5 C was circulated.
- the powder 972 (di) -4 obtained was added and mixed to obtain an electrostatically charged toner.
- the properties and values of the obtained electrostatic charges were measured in the same manner as in the embodiment. The results are shown in the table.
- the charge toner in the comparison is within the range defined by the light, the charge toner in the comparison is within the range defined by the invention, and the charge toner in the comparison 2 has the low hot-setting temperature and the print quality. However, especially after being left at a temperature of 5 C and a humidity of 82, the printability is low, the environmental preservation is low, the storage is low, and the king property is low. On the other hand, the charge toner of No. 2 has a high hot-setting temperature, a high printing degree, good environmental preservation, preservability and good king quality.
