ABSTRACT:
Wet-type electrostatic photographic transferring method is disclosed, comprising developing an electrostatic latent image formed on an image-carrying member with an electrostatic photographic liquid developer containing at least toner particles and a carrier liquid, and transferring the toner image from the toner image-carrying member to a member to which the image is to be transferred, by one transferring step or a plurality of transferring steps, characterized in that the transferring step includes at least the following steps: (1) a step to substantially dry the toner image; (2) a step to supply a non-aqueous solvent having a volume resistance of at least 10.sup.9 .OMEGA..multidot.cm and a dielectric constant of not more than 3 into a clearance between the toner image-carrying member and the member to which the image is to be transferred; and (3) a step to transfer the toner image to the member to which the image is to be transferred.
