    摘要: A full-color electrophotographic apparatus of the present invention is configured such that a toner image is formed on an intermediate transfer member. The intermediate transfer member is heated to a temperature equal to or higher than the softening start temperature of resin contained in a liquid toner and equal to or lower than the withstand temperature of a photoconductor member. A carrier-removing roller to which bias can be applied abuts the intermediate transfer member so as to remove a carrier while packing softened toner by the force of an electric field induced by bias. In a transfer section for transfer to a printing medium, a backup roller presses the printing medium against the intermediate transfer member, and the toner image is transferred from the intermediate transfer member to the printing medium. Before being pressed against the toner image on the intermediate transfer member, the printing medium is heated. Bias is applied to the backup roller such that the toner image on the intermediate transfer is attracted toward the printing medium by the action of an electric field, thereby assisting transfer. By so doing, the intermediate transfer member does not need to undergo cooling before coming into contact with the photoconductor member, thereby avoiding occurrence of thermal damage to the photoconductor member.
