Abstract
In a wet recording apparatus comprising: an image bearing structure; a developing solution prepared by dispersing charged color material particles in a dispersion medium; an ion generating unit; and ion current control units, the developing solution is applied to the image bearing structure to form a developing solution layer thereon, the ion current controlling unit operates to cause ions produced by the ion generating unit to stick selectively to the surface of the developing solution layer, to form a color material image on the image bearing structure, and the color material image is transferred, as a toner image, onto a recording sheet.
