Abstract
An image forming method wherein a toner image on an image carrier is transferred in a first transfer step to an intermediate image transfer element, the transferred toner image on said intermediate image transfer element being subsequently transferred in a second transfer step to a transfer medium. The intermediate image transfer element has a surface whose angle of contact with water is at least 70 degrees and whose position in the triboelectric series is on a positive side with respect to the position of said toner when the toner on the image carrier is negatively charged and on a negative side with respect to the position of the toner when the toner on the image carrier is positively charged.
