Title:
分離装置
Document Type and Number:
Japanese Patent JP7130477
Kind Code:
B2
Abstract:
Provided is a separator for separating toner and a carrier liquid from a liquid developer, 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; a first voltage application unit which applies voltage to the electrode member; a second voltage application unit which applies voltage to the recovery roller; and a control unit which performs control such that the application of voltage to the recovery roller by the second voltage application unit is initiated after initiating the supply of the liquid developer by the supply part and initiating the rotation of the electrode roller and the recovery roller, and such that the initiation of voltage application to the electrode member by the first voltage application unit is before the initiation of voltage application to the recovery roller by the second voltage application unit. Thus, the maintenance load for a separator for separating toner and a carrier liquid from a liquid developer is reduced while improving the efficiency with which the toner and carrier liquid are separated from the liquid developer.
