Patent ID: 8274540

Claim:
An image forming apparatus comprising: a photoconductive body on which an electrostatic latent image is configured to be formed; an exposure unit including a plurality of blinking sections each of which being configured to emit a light to expose the photoconductive body; a first pressing member configured to press the exposure unit toward the photoconductive body; a first positioning member configured to be brought into contact with the exposure unit to position the exposure unit in a movement direction of a portion, of the photoconductive body, facing the exposure unit; a second positioning member which is arranged closer to the photoconductive body than the first positioning member in an optical axis direction of the light, the second positioning member configured to make contact with the exposure unit and to position the exposure unit in the movement direction; and a second pressing member configured to press the exposure unit toward the second positioning member, wherein one of the first positioning member and the second positioning member is arranged at an upstream side in the movement direction with respect to the exposure unit, and the other of the first positioning member and the second positioning member is arranged at a downstream side in the movement direction with respect to the exposure unit; wherein a portion, of the second pressing member, at which the second pressing member presses the exposure unit is positioned at a first position or a second position the first position facing both of the second positioning member and the exposure unit, and a second position being closer to the photoconductive body than the second positioning member; and wherein a point of action at which the first pressing member presses the exposure unit is located at a position closer to the photoconductive body than the first positioning member in the optical axis direction.
