Abstract
A wet-type image formation apparatus includes: an intermediate transfer body that carries a toner image including toner particles, which are charged to have a first polarity, and a carrier liquid; a transferring roller that transfers a toner image onto a transfer surface of a recording medium; a charging device that charges the transfer surface to have a second polarity opposite to the first polarity; and a fixing mechanism that fixes the toner image. The fixing mechanism includes a noncontact heating device. The noncontact heating device forms the toner particles into a film such that the toner particles and the carrier liquid are separated from each other by heating the toner image when the toner particles charged to the first polarity is electrostatically adsorbed onto the transfer surface charged to have the second polarity. The film of the toner particles is fixed onto the transfer surface.
