Image formation apparatus that changes a voltage to secondary transfer units based on arrangement of image formation units

摘要

An image formation apparatus includes: image formation units each configured to form a developer image; an intermediate transfer body onto which the developer images formed by the respective image formation units are transferred; a secondary transfer member configured to transfer the developer images, which are transferred to the intermediate transfer body, onto a record medium using a voltage supplied to the secondary transfer member; and a voltage supply unit configured to supply a voltage to the secondary transfer member. Arrangement of the image formation units is changeable. Depending on the arrangement of the image formation units in a conveyance direction of the intermediate transfer body, the voltage supply unit changes a voltage to be supplied to the secondary transfer member.
