Toner, method for manufacturing the toner, method and device for packing the toner, and image forming apparatus using the toner

摘要

A method for producing a toner including dissolving or dispersing a toner constituent mixture including a binder resin and a colorant in an organic solvent to prepare a toner constituent mixture liquid; dispersing the toner constituent mixture liquid in an aqueous medium including a particulate dispersant to prepare an emulsion; and removing the organic solvent from the emulsion while applying a shearing force to the emulsion. A toner manufactured by the method and having a spindle form while satisfying specific particle diameter relationships. An image forming apparatus using the toner. A toner packing method and device in which the toner is fluidized and pressurized to be fed from a fluidizing container to a toner container on which a gas-powder separation sieve is set to discharge air therefrom.
