Claim:
1. An image forming apparatus comprising: a light source configured to emit a light beam for exposing a photoconductor; a rotating mirror configured to deflect the light beam so that the light beam scans the photoconductor; an optical box where the light source and the rotating mirror are disposed; a cover attached to the optical box, the cover including a transparent window which the light beam deflected by the rotating mirror passing therethrough and a recess at which a connection portion is provided; a shutter which slides so as to reciprocate between a position on a light path of the light beam that has passed through the transparent window and a position off the light path of the light beam that has passed through the transparent window; a shutter moving mechanism including pushing unit and a spring, the pushing unit pushes the shutter to slide, the spring being connected to the connection portion and the shutter so as to urge the shutter in a direction opposite to a pushing direction of the pushing unit, and sliding the shutter in the opposite direction by elastic force; wherein the recess is recessed toward an inner side of the optical box, and the recess is further recessed than a position of a surface of the cover which is disposed on an extension of a rotational axis of the mirror.
