Method of manufacturing toner, apparatus of manufacturing a toner, a toner, an image forming method and an image forming apparatus

An apparatus of manufacturing a toner, comprising:

• an emulsifying facility for continuously emulsifying a dispersion of at least two binder resins having different weight-average molecular weight, a coloring agent and a releasing agent in an organic solvent (oil phase) in an aqueous medium includes a solid particulate dispersion agent;
• wherein the emulsifying facility comprising a means for dispersing under a condition based on at least one property of the binder resin which has the lowest weight-average molecular weight;
• a means for automatically measuring the volume particle diameter of the dispersion emulsion during the dispersing;
• a means for calculating a difference between the volume average particle diameter of the dispersion emulsion measured during the measuring, and a target volume average particle diameter;
• a means for receiving a signal for controlling the process of manufacturing;
• wherein the signal is calculated from a relation between the information about the difference between the volume average particle diameter of the dispersion emulsion measured during the measuring, and a target volume average particle diameter calculated by the means for calculating and a difference between a volume average particle diameter of a dispersion emulsion measured during the measuring, and a target volume average particle diameter as well as a condition for process inputted in the computer beforehand;
• a means for automatically controlling the process of manufacturing;
• a means for collecting the emulsification particles that satisfy the required volume average particle diameter.
