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.

Abstract: An image is exposed to light after a conductive and photoconductive material has been charged so that the charge of the portion exposed to light is neutralized and a latent image is thereby formed. Toner particles in a liquid developer are adsorbed onto the non-exposed portion so that development is performed. Then, the toner particles are dried by a drying device and thus aggregated toner particles are transferred to a transferring material due to an electrostatic force. Since the toner image is temporarily dried and is transferred in the aggregated form corresponding to the shape of the image, image disorder due to liquid fluidization that takes place at the time of liquid transference can be prevented. Therefore, a high quality transferred image is obtained.

Abstract: A liquid developer for development of electrostatic latent images comprising a carrier liquid containing at least one copolymer of formula (I): ##STR1## wherein R.sub.1 is a hydrogen atom or a methyl group; R.sub.2 is an alkyl, aralkyl, aryl or cycloalkyl group, which may be substituted; and x and y eash is a number to satisfy the condition of x/y=0.995 to 0.80/0.005 to 0.20 on a molar basis. By incorporation of the copolymer, the transferability, dispersibility and fixability of the developer are improved.
