Abstract:
A duplex image transferring method comprising:a first step of bringing one side of a recording medium into contact with a first toner image, which is formed on a first image carrier by a colored liquid containing toner and a carrier liquid, and causing a first electric field to act toward said recording medium in a forward direction to thereby transfer said first toner image to said one side of said recording medium, while causing a toner layer gathered at said recording medium and a carrier liquid layer left on said first image carrier to part from each other; and a second step of bringing the other side of said recording medium into contact with a second toner image formed on a second image carrier by the color liquid while maintaining the first toner image, in which the liquid carrier layer contains the carrier liquid of an amount not great enough to serve as an electrophoresis medium for the toner layer, but sufficient to serve as a parting agent for said toner layer and a contact member contacting said toner layer, on the one side of said recording medium, and causing a second electric field, which acts toward said recording medium and forward for said second toner image, but reverse for said first toner image, to act on said second toner image and said first toner image to thereby transfer said second toner image to said other side of said recording medium.
