PROBLEM TO BE SOLVED: To give an enough mechanical strength to the housing of an image forming apparatus in spite of using its side-plated made of a sheet metal whose manufacturing cost is cheap, and to make easy the junctions of its front and rear side-plates to its base member. SOLUTION: The housing of an image forming apparatus has front and rear side-plates 3, 4 provided in parallel with each other and has a base member 2 joined to the lower portions of both the side-plates 3, 4 which supports both the side-plates 3, 4. Both the side-plates 3, 4 are made of a sheet metal. Joint margins 33, 35, 43, 45 are so formed by folding the side portions of both the side-plates 3, 4 as to weld the lower portions of the joint margins 33, 35, 43, 45 to the side surfaces of angle pipes 21 of the base member 2.
