example 1
[0230] A resin solution A and a dispersion B were prepared.
[0231]
[0232] In a sealable container equipped with stirring blades, add the following materials by weight: 98 parts of polyester resin (acid value: 26.2KOHmg / g; hydroxyl number: 12.2KOHmg / g; glass transition temperature: 62 ° C; downstream flow Gauge softening temperature: 104.8° C.), 6 parts of quinacridone-based dye, and 100 parts of methyl ethyl ketone. Then the stirring blade is rotated to obtain resin solution A.
[0233]
[0234] Into a sealable container with zirconia beads was added the following materials by weight: 2 parts zinc salicylate, 3 parts carnauba wax, 2 parts polyester resin, and 300 parts methyl ethyl ketone. Then, in the sealable container, these materials were subjected to ball mill dispersion for 1 hour to obtain a dispersion B.
[0235] Then, the dispersion liquid B thus prepared was added to the resin solution A thus prepared. Then, the mixture was stirred for 10 minutes to obtain...
example 2
[0244]A liquid starting material 6 was prepared containing 6 parts by weight of a quinacridone-based dye and 2 parts by weight of salicylic acid dispersed in 100 parts by weight of molten polyolefin resin acid zinc. The starting material thus obtained had a viscosity of 210 centipoise at 120°C.
[0245] Then, the thus-obtained starting material is fed into a feeder of a toner production apparatus such as figure 1 and figure 2 shown. Then the starting material received by the feeder is added to the starting material storage part of the head through the metering pump. Then, the starting material is sprayed from the spraying section into the curing section. The ejection part is a circular structure with a diameter of 25 μm.
[0246] The injection of the starting material is realized under the following conditions: the temperature of the starting material in the head is 120 °C, the frequency of the piezoelectric material is 1 MHz, and the initial velocity of the starting mat...
