Title:
METHOD OF MANUFACTURING DEVELOPER
Document Type and Number:
Japanese Patent JP2011053556
Kind Code:
A
Abstract:
To provide a method of manufacturing a developer having homogeneous particle size without using an organic solvent.
This method of manufacturing the developer has a possess of atomizing toner material particles by passing dispersion liquid through a high voltage homogenizer device having a nozzle part having an orifice part. Dissipation energy E is expressed by 1.0×1013≤ΔP×u/(2.5d)≤5.0×1014(J/m3s). Here, ΔP is difference (Pa) between pressures in front of the orifice part and in the orifice part, u is flow rate (m/s) in the orifice part, and d is orifice diameter (m).
