Title:
SEPARATOR
Document Type and Number:
WIPO Patent Application WO/2020/013342
Kind Code:
A1
Abstract:
The present invention increases the efficiency with which toner and a carrier liquid are separated from a liquid developer. Provided is a separator which separates toner and a carrier liquid from a liquid developer. Specifically provided is a separator for separating, using an electric field, toner and a carrier liquid from a liquid developer containing the toner and carrier liquid, wherein the separator comprises: an electrode roller; an electrode member which is disposed such that there is a gap between the electrode member and the outer circumferential surface of the electrode roller, and in which voltage that generates an electric field for moving the toner to the electrode roller side can be applied across the electrode member and the electrode roller; a supply part which supplies the liquid developer to the aforementioned gap; a carrier recovery part which is provided adjacent to the downstream side of the electrode member in terms of the rotation direction of the electrode roller and recovers the carrier liquid; a recovery roller which is disposed further downstream than the carrier recovery part in terms of the rotation direction of the electrode roller, and in which voltage that generates an electric field for moving the toner from the electrode roller side can be applied across the recovery roller and the electrode roller; and a control unit which performs control such that the supply of the liquid developer by the supply part is stopped, then the application of voltage across the electrode member and the recovery roller is stopped, and thereafter the rotation of the electrode roller and the recovery roller is stopped. The present invention thereby increases the efficiency with which the toner and the carrier liquid are separated from the liquid developer.
