PURPOSE: To unnecessitate a plate making process and to easily process a dyed image to be formed by electronic image processing by developing an ion pattern formed on an ion image recording body by wet developer containing a specified coloring material.

CONSTITUTION: A high-frequency voltage is impressed between the line electrode 7 and the finger electrode 8 of a recording head 2. By an electric field formed between the electrode 8 and a dielectric drum 3, an ion flow 10 is formed and an electrostatic image by ion is formed on the drum 3. Then, the electrostatic image formed on the drum 3 as a latent image is developed by the wet developer in a developing device 5. The wet developer is obtained by dispersing a resin grain consisting of dye shifted by being melted, diffused or sublimated by heat, fixing agent, electric charge control agent and dispersion stabilizer in electric insulating liquid. Then, textile printing is executed by transferring a toner image on the recording medium 12 consisting of cloth or texture, etc., by a transfer roller 6.
