between rollers 2 and 7, 7', a heated transfer roll 3, a pressure roller 4, LID development device 5 and blotting rollers 6 as disclosed in the figure. As materials used for the heated transfer roller 3 or the pressure roller 4, typically a liquid absorbable silicone rubber roller, is preferred. In the LID developing device relatively high vapor pressure liquid (luquid) such as NorparTM or the like is used. The duplex image forming process is conducted as follows: Primarily, the silicone rubber Intermediate Transfer Belt (ITB) on the developing device 5 is maintained at a saturated condition of the NorparTM or near so. The toner image is transferred electrostatically to the belt 1, some blotting may then be required to increase the toner % (solid) in the image as indicated at a medium liquid content. Liquid content might otherwise occur naturally during sustained operation since the roll is "blotted" continually by the paper media. The image is then transferred to the media or transferred to the pressure roller which is maintained at an even lower level of liquid absorption than the heated transfer roller 3. In this case, both rolls need to be h...
