<p>PURPOSE: To provide a producing method of a dyeing particle as a raw material of a toner improved in various properties and capable of obtaining a stable picture. CONSTITUTION: A coarse dyeing material B supplied to a raw material supply part 9 is sucked and accelerated to Mach >=2.5 by a compressed air 7 and flying out from the tip 6a of a nozzle 6 to collide with a collision plate 4. Aggregates (b) contained in the coarse dyeing material B is cracked into the dyeing particle C and after that, the dyeing particle is discharged from a discharge part 5 with the flow of the compressed air 7.</p> |
