    摘要： An image forming apparatus of the present invention is operable in a duplex print mode for printing images on both sides of a recording medium. A toner image is transferred from a first image carrier (1) to a second image carrier (10) and then transferred from the second image carrier to one side of the recording medium. Subsequently, a toner image is transferred from the first image carrier to the other side of the recording medium. After the toner image has been transferred from the first image carrier to the second image carrier, the second image carrier is moved in the reverse direction to a preselected position. The apparatus of the present invention enhances productivity in the duplex print mode. Furthermore, the polarity of the charge of the image carried on said second image carrier (10) is inverted. The second image carrier (10) is a belt with a mechanism to prevent offset.

    摘要： In an image forming apparatus provided with a first image carrying member; a belt-shaped second image carrying member onto which a toner image is transferred from the first image carrying member; a pair of rotatable fixing members forming a nip region for fixing the toner images transferred on the both sides of the sheet; a conveying device for guiding the sheet separated from an end of the belt-shaped second image carrying member to the pair of rotatable fixing members, when the sheet is nipped and conveyed through the nip region of the pair of rotatable fixing members, the belt-shaped second image carrying member and the pair of rotatable fixing members are arranged such that the sheet is conveyed so as to form a loop protruding from a line connecting the entrance of the nip region and the end of the belt-shaped second image carrying member.

    摘要： The digital printing process includes the printing of liquid toner on both substrate sides. Thereto developed portions of a first and a second liquid toner are transferred to the first side and fused by exposure to infrared radiation and by subsequent contact fusing. The substrate is conditioned for a further transfer step by maintaining a substantially uniform water content therein during and after the fusing step, in which further transfer step at least one further developed portion of liquid toner is transferred to a side of the substrate. This occurs particularly by limiting heat development in the liquid toner, such as by using a black toner liquid with an absorbance at 800 nm of at most than 0.8.
