PURPOSE:To perform positioning with high accuracy at the time of assembly and to readily obtain an appropriate image by integrally composing image reading and exposing elements for a second exposing means. CONSTITUTION:This device employs one obtained by integrally assembling the image reading element 8 and the exposing element 11 for the second exposing means 15 to a fitting member 30. Since the second exposing means 15 is properly placed on an optical path and a photosensitive drum 7, a joined optical system 6 forms an analog, electrostatic latent image, and simultaneously at the same timing the exposing element 11 erases a latent image corresponding to a color component. Thus, they can be positioned with high accuracy at the time of assembly to readily obtain an appropriate image. |
