Unit assembly and image forming apparatus

摘要

A unit assembly (10) includes an image forming unit (20) and an intermediate transfer unit (40), and is configured insertably/removably with respect to an apparatus main body. The image forming unit (20) includes a plurality of process units (200A to 200D) and a joint member (80) that joints the plurality of process units (200A to 200D). The intermediate transfer unit (40) is held by the image forming unit (20). The intermediate transfer unit (40) and the joint member (80) have a first positioning section (611, 612) for mutually relative positioning.
