Abstract:
An image forming apparatus, comprising:a photoreceptor having an image carrying surface; an exposing device to imagewise expose the image carrying surface to form a latent image; and a developing device to develop the latent image to form a toner image on the image carrying surface; the exposing device comprising: a light source to emit a light beam; a deflector to deflect the light beam so as to form a scanning line with the light beam on the image carrying surface; a cylindrical lens provided between the deflector and the image carrying surface and to focus the light beam on the image carrying surface; and an adjusting mechanism to adjust an inclination of the scanning line and to adjust variance in magnification of an image on the scanning line, wherein the exposing device comprises a unit housing in which the light source, the deflector, and the cylindrical lens are mounted, and wherein the adjusting mechanism comprises first, second and third supporting members to support three different supporting points of the unit housing, a first adjusting member and a second adjusting member, and the adjusting mechanism adjusts the inclination of the scanning line by moving the first adjusting member and adjusts the variance in magnification by moving the second adjusting member.
