The image forming apparatus includes a first placement member, a second placement member, a third placement member and a fourth placement member, which contact with a placement surface on which the image forming apparatus is placed, and which support the image forming apparatus, a side plate of the image forming apparatus, and a supporting section for supporting the image forming apparatus. The supporting section is supported by the third placement member and the fourth placement member, which are movable in a vertical direction of the image forming apparatus. This can prevent the deformation of the image forming apparatus without increasing the load on a bottom plate.
