Abstract:
1. An image forming apparatus, comprising: a photosensitive member; an exposure unit configured to emit a light beam based on image data to form an electrostatic latent image on the photosensitive member; a placement unit configured to support the exposure unit, wherein the placement unit is fixed to a body of the image forming apparatus; an elastic member placed on the placement unit, the exposure unit being placed on the elastic member so that the elastic member is disposed between the exposure unit and the placement unit; a positioning member fixed to the body of the image forming apparatus and configured to be in contact with the exposure unit so that the elastic member is pressed by the exposure unit toward the placement unit, wherein a position of the exposure unit in a direction of gravity is regulated by the positioning member; and an adjustment unit configured to adjust a compression amount of the elastic member in the direction of gravity, wherein the adjustment unit includes: a cam configured to be brought into contact with the elastic member and to convert a movement in a horizontal direction into a movement in the direction of gravity; and a movement amount changing unit mounted on the placement unit so as to be brought into contact with the cam and configured to change the movement of the cam in the horizontal direction.
