Patent ID: 7651212

Claim:
An image forming apparatus, comprising: an ink ejection device which ejects a droplet of radiation-curable ink onto a recording medium; a solvent separating device which separates a coloring material component from a solvent component in the droplet of the radiation-curable ink on the recording medium by using an electrophoresis effect; a solvent removing device which removes the solvent component separated by the solvent separating device; and a curing device which irradiates radiation onto the droplet of the radiation-curable ink after the solvent component is removed by the solvent removing device, in such a manner that the droplet of the radiation-curable ink is cured, wherein the solvent separating device includes: an electrically charging device which electrically charges the droplet of the radiation-curable ink on the recording medium; a recording medium holding member on which the recording medium is held; and an electric field application device which applies an electric field to the electrically charged droplet on the recording medium held on the recording medium holding member, the electric field application device having a DC power source which is electrically connected to the solvent removing device and the recording medium holding member and applies a DC voltage between the solvent removing device and the recording medium holding member.
