METHOD OF PRODUCING TONER

A method of producing a toner includes preparing a resin solution containing a binder resin, a colorant and an organic solvent; forming a droplet, a surface of the droplet being covered with a resin fine particle L1; introducing a resin fine particle L2; pressuring by introducing carbon dioxide, and...

Zusammenfassung:A method of producing a toner includes preparing a resin solution containing a binder resin, a colorant and an organic solvent; forming a droplet, a surface of the droplet being covered with a resin fine particle L1; introducing a resin fine particle L2; pressuring by introducing carbon dioxide, and extracting the organic solvent in the droplet; and obtaining the toner particle by removing the carbon dioxide together with the extracted organic solvent, wherein the SP value of the resin R1 constituting the resin fine particle L1 and the SP value of the resin R2 constituting the resin fine particle L2 are each within a specific range.
