Abstract: PROBLEM TO BE SOLVED: To provide the supporting structure of an image forming device capable of improving both a strength and a dimensional accuracy and capable of also corresponding to even an enlargement.
SOLUTION: Since U-shaped steel materials for each support member 42 to 45 and each connecting member 51 to 56, 61 to 67 and 71 to 76 are separately connected successively, the supporting structure 41 can be assembled up, offsetting the distortions of each support member and each connecting member, and the dimensional accuracy of the supporting structure 41 can be improved. The U-shaped steel materials are proper to support a load in the vertical direction. Each connecting member 51 to 56, 61 to 67 and 71 to 76 fills the roles as bracings among each support member. Accordingly, the strength of the whole of the supporting structure 41 is increased extremely, and the distortion of the whole of the supporting structure 41 is reduced.
