摘要： An electrophotographic liquid-developing method comprising controlling the polarity of the toner by varying the mixing proportion of the dispersion media and/or the temperature of the developer solution. An electrostatic charge-substrate having an electrostatically charged latent image is immersed in the developer solution to convert such latent image into a visible image. Said developer solution comprises a toner consisting of pigment particles and at least one resin selected from the group consisting of alkyd resin, phenol resin and vinyl resin, and a carrier liquid in which said toner is dispersed. The carrier liquid comprises a mixture of two dispersion media having different affinities to said resin. Dispersion media having a larger affinity to the resin include halogenated hydrocarbons, aromatic hydrocarbons and petroleum hydrocarbons containing aromatic ingredients. Dispersion media having a smaller affinity to the resin include isoparaffinic and paraffinic hydrocarbons.
