ABSTRACT:
An image forming apparatus includes a plurality of image carriers and a transfer assembly. The transfer assembly includes a plurality of transferees, a supporter, and a plurality of transferee holders. The plurality of transferers is each configured to electrostatically transfer a toner image carried on one of the image carriers onto an intermediate transfer member or a recording medium. The supporter is configured to support the transferers. The transferer holders are each configured to hold one of the transferers. Each of the transferee holders and the transferer held thereby form an integrated individual unit independently attachable to and detachable from the supporter.
