Particles and manufacturing method thereof, toner and manufacturing method thereof, and developer, toner container, process cartridge, image forming method and image forming apparatus

摘要

The present invention provides a method for manufacturing particles, where a viscous material is sprayed with a high-pressure gas for atomization while the viscous material is being discharged in a chamber, and cooling air is introduced in the chamber for granulation. The present invention also provides a method for manufacturing a toner, where a mixture containing at least a binding resin and a colorant is melt mixed under pressure or melt mixed with an injection of a supercritical fluid, the obtained melt-mixed substance is sprayed with a high-pressure gas for atomization while the melt-mixed substance is being discharged in a chamber, and cooling air is introduced in the chamber from an air inlet formed on the chamber.
