Abstract
Method and apparatus for transferring an electrostatically deposited electrophoretic toner image including the step of transferring image-wise deposited toner particles dispersed in a stratum of carrier liquid having a volume resistivity of at least 10.sup.9 ohm.cm and a dielectric constant less than 3 from an electrically insulating surface onto a receptor element by contacting said liquid stratum while carried on the insulating surface with a surface of the receptor element while applying an electric field such that the receptor element has a polarity opposite to the polarity of the toner particles to effect such transfer, characterized in that before the image-wise liquid stratum touches the receptor element the carrier liquid stratum is given a corona-charge treatment by a corona-charge unit whereby said liquid stratum is charged to a polarity opposite to the charge of the toner particles.
