摘要： An image forming apparatus includes a photoconductive body on which an electrostatic latent image is formed, an exposure unit which exposes the photoconductive body, a first pressing member which presses the exposure unit toward the photoconductive body, a first positioning member which makes a contact with the exposure unit, a second positioning member which is arranged at a side nearer to the photoconductive body than the first positioning member in an optical axial direction of light, and a second pressing member which presses the exposure unit toward the second positioning member. A point of action at which the first pressing member presses the exposure unit is positioned at a side nearer to the photoconductive body, than the first positioning member in the optical axial direction. It is possible to suppress a degradation of an image quality by suppressing an effect of vibrations with respect to the exposure unit.
