Title:

PROCESS FOR PRODUCING LIQUID DEVELOPING AGENT, AND LIQUID DEVELOPING AGENT

Document Type and Number:

WIPO Patent Application WO/2006/075746

Kind Code:

A1

Abstract:

This invention provides a liquid developing agent, which has a narrow particle size distribution width, has a uniform shape, and is excellent in fixation of toner particles to a recording medium, and a liquid developing agent, which has a narrow particle size distribution width, has a uniform shape, and enables the properties of each component constituting the toner particles to be satisfactorily exhibited, a liquid developing agent having excellent offset resistance (releasability), and a process for producing a liquid developing agent which can efficiently produce the above liquid developing agent. In particular, the above liquid developing agent is provided by an environmentally friendly process. The process for producing a liquid developing agent comprises the step of providing an aqueous dispersion liquid comprising a dispersoid, comprising a resin-containing material, dispersed in an aqueous dispersing medium comprising an aqueous liquid, and the step of spraying the aqueous dispersion liquid as droplets to remove the aqueous dispersing medium and to disperse toner particles, obtained as an aggregate of a plurality of pieces of dispersoid contained in the droplets, directly in the insulating liquid.
