Unit assembly and image forming apparatus

摘要

A unit assembly (10) is provided with an image forming unit (20) and an intermediate transfer unit (40), and is configured to be capable of being inserted into and removed from an apparatus body (110). The image forming unit (20) has first processing units (200A to 200D), developing units (4A to 4D), a positioning portion, and a link member (80). The positioning portion is provided in each of the developing units (4A to 4D) and determines the mutual relative positions of the developing units (4A to 4D). The link member (80) links the developing units (4A to 4D) to each other. The intermediate transfer unit (40) is held by the image forming unit (20).

主权项

1. A unit assembly configured to be capable of being inserted into and removed from an apparatus body of an image forming apparatus that performs an electrophotographic image forming process, the unit assembly comprising:
an image forming unit that has:
a plurality of first processing units that each include a first image forming member among a plurality of image forming members that form a developer image;a plurality of second processing units that each include a second image forming member among the plurality of image forming members and hold the plurality of first processing units, respectively;a positioning portion that determines mutual relative positions of the plurality of second processing units; anda link member that links the plurality of second processing units together in a state in which the mutual relative positions of the plurality of second processing units are determined with respect to each other; and an intermediate transfer unit that bears the developer image formed by the plurality of image forming members and carries the developer image to a position in which the developer image is transferred onto a sheet of paper, the intermediate transfer unit being held by the image forming unit, wherein the second processing units are developing units.
