The method comprises the steps of: preparing a kneaded material containing a coloring agent and a resin material; dispersing the kneaded material into an insulation liquid to obtain a molten state kneaded material dispersed liquid in which the kneaded material in a molten state is finely dispersed; and cooling the molten state kneaded material dispersed liquid to solidify the molten state kneaded material; wherein the insulation liquid contains as its major component an unsaturated fatty acid. According to the method, it is possible to provide a liquid developer in which toner particles having a small particle size distribution and a uniform shape are dispersed so that properties of each component of the toner particles can be exhibited sufficiently.

摘要： Disclosed are a two-component type developer which is supplied to an area where a bias voltage of at least 250 V is applied, and a developing process using this developer. In this developer, by adjusting the particle size distribution of carrier particles within a specific range, occurrence of the so-called carrier dragging phenomenon of the transfer of the carrier together with the toner to a photosensitive material can be prevented. This adjustment of the particle size distribution is such that the content of carrier particles having a size smaller than 250 mesh is less than 8% by weight based on the entire carrier particles, the diameter D.sub.50 of the weight average particle size corresponding to 50% of the weight of the entire carrier particles is in the range of from 80 to 120 .mu.m and the difference between D.sub.25 and D.sub.75 is in the range of from 5 to 20 .mu.m.
