Abstract
Abstract The present invention relates to an intermediate transfer material, used for an image forming method of developing an electrostatic latent image on an electrostatic latent image carrier utilizing a liquid toner, electrostatically transferring the image visualized by development onto an intermediate transfer material, and re-transferring visible image from the intermediate transfer material onto final transfer objects, utilizing as the intermediate transfer material at least a silicone rubber layer, an adhesive layer and a conductive fluorine rubber layer in this order from the outer surface side thereof. The intermediate transfer material of the present invention is excellent in durability and transferability, and so the image forming method using said intermediate transfer material can provide a high quality image at high reproducibility.
