記載の転写装置。[Claims for Utility Model Registration] (1) Toner images formed on a plurality of photoconductors are transferred to the same transfer paper conveyed by a transfer belt made of a dielectric material that rotates in sequential contact with these photoconductors. ,
In a transfer device of an image recording apparatus that records images by sequentially overlapping transfer under the action of a transfer charger disposed opposite to a photoreceptor while sandwiching the transfer belt, the transfer paper is transferred from immediately after the most upstream transfer position. A transfer device characterized in that a conductive member is disposed close to the back surface of the transfer belt until it leaves the transfer belt. (2) The above transfer charger consists of a corona discharge wire stretched within a shield plate extending in the width direction of the photoreceptor, and between the edge of the shield plate and a point on the back surface of the transfer belt directly above the edge of the shield plate. 2. The transfer device according to claim 1, wherein the distance is greater than or equal to the distance between the point on the back surface of the transfer belt and the edge of the conductive member.
