Abstract
Colored resin particles, each includes: a resin; and a colorant, wherein a value of average equivalent circle diameter A (μm) of the colored resin particles is 3≦A≦6, an average degree of circularity B of the colored resin particles satisfies the following expression (1), and 0.990−0.0083A≦B≦1.021−0.0117A (1) a cumulative number frequency of particles which have degrees of circularity of less than 0.9 in the colored resin particles is 1% or less.
Claims15
A manufacturing method of colored resin particles, the method comprising:
- preparing a reactor that includes a first channel, a second channel, a first confluent channel where the first channel and the second channel converge and a temperature control unit that controls a temperature of the first confluent channel;
- feeding a coagulated particle dispersion containing coagulated particles that contain resin particles and a colorant to the first channel;
- stopping growth of coagulation of the coagulated particles by feeding a liquid containing a coagulation stopper from the second channel;
- and
- coalescing the coagulated particles by heating the first confluent channel.
