The image forming apparatus including an exposure unit that exposes an image bearing member by a laser beam, a first side plate and a second side plate facing with each other, and a first support member, a second support member, and a third support member connecting the first side plate and the second side plate to each other, wherein the first side plate and the second side plate and the first support member, the second support member, and the third support member form a substantially closed space, with said exposure unit being arranged in the closed space, and wherein a section of the closed space on a plane parallel to the first side plate and the second side plate has a substantially triangular shape. It achieves preventing the displacement of an optical component attributable to an increase in size of the image forming apparatus main body and twisting of side plates. |
