Image forming apparatus and method for assembling the same

摘要

This invention relates to an image forming apparatus and a method for assembling the apparatus. A main body of the image forming apparatus has a frame main body consisting of an optical frame and a chassis made of a resin (resin chassis). Mounting an image recorder unit on the resin chassis improves the precision in mounting the image recorder unit, while the optical frame assuring the rigidity of the apparatus as a whole. The resin chassis consisting part of the frame main body reduces the production cost of the frame main body, in turn, reducing the production cost on the final product, i.e., image forming apparatus.
