    摘要: An oil removing device includes a first heating member that at an outer surface thereof contacts a non-image surface of a recording medium which is transported, and that heats the recording medium, a toner image that is formed by using liquid developer that contains volatile oil and toner being transferred to the recording medium; and a second heating member that is disposed on a downstream side of the first heating member in a transport direction, the second heating member contacting at an outer surface thereof the non-image surface of the recording medium and heating the recording medium. In the oil removing device, a non-contact region where the non-image surface of the recording medium does not contact the first heating member and the second heating member is provided between the first heating member and the second heating member.

    摘要: In one example, a system for transferring an image from a photoconductor to a print substrate includes a transfer member having a removable blanket wrapped around a rotatable drum and a laser. The blanket has a light absorbing exterior surface to receive a liquid LEP ink image from the photoconductor and to release a layer of molten toner to a print substrate. As the drum rotates, the laser exposes a width of the exterior surface of the blanket carrying a liquid LEP ink image to a beam of coherent light that delivers enough power to transform the liquid LEP ink image into molten toner.

    摘要: An image forming apparatus includes a fixing device that fixes a toner image which is developed with a liquid developer containing a toner and a volatile carrier oil on a recording medium, a heating device that is disposed on an upstream side of the fixing device in a feed direction of the recording medium, and heats the toner image on the recording medium in a non-contact manner, in which heating is controlled such that a porosity of the toner image on the recording medium in an outlet of the heating device is in a range of 20% by volume to 40% by volume, and a drying path that is disposed between the heating device and the fixing device in the feed direction of the recording medium, and dries the recording medium by evaporating the carrier oil in the recording medium.
