Provided is an image forming apparatus support structure which permits improvements in both strength and dimensional accuracy, and which can also accommodate increases in size. Because respective coupling member(s) and steel channel of respective post member(s) may be sequentially and individually connected, it is possible to improve support structure dimensional accuracy, it being possible to assemble support structure(s) such that deviation(s) in the respective coupling member(s) and the respective post member(s) offset(s) one another. Furthermore, steel channel is suitable for supporting load(s) in vertical direction(s). Moreover, respective coupling member(s) may serve as brace(s) when interposed between respective post members. Where this is the case, strength of the overall support structure may be made extremely high, and strain exhibited by the overall support structure may be reduced.
