Abstract

An optical system assembling method in an image forming apparatus in which there are provided an image forming body around which a plurality of exposure device each having a linear exposure optical system to imagewise expose on the image forming body, and a plurality of developing device containing respective color toners different from each other which are superimposed on the image forming body to form a color toner image, the method further having the steps of: lighting the exposure optical system; forming an image emitted from the exposure optical system on a sensor which is disposed at a position corresponding to a photosensitive surface of the image forming body with respect to the exposure optical system; adjusting a position of the exposure optical system on the basis of a result of the image forming so that a focal point of the exposure optical system is coincident with a surface of the sensor; and fixing at the adjusted position the exposure optical system to an optical system supporting body provided on a main body of the apparatus.
