照明装置。[Claims for Utility Model Registration] (1) A plurality of point light sources arranged in a row at predetermined intervals are arranged so as to face the surface of the image carrier, and each point light source illuminates the image. In an illumination device that illuminates a carrier to erase unnecessary charges on the image carrier, a reflecting member is provided near the point light source to reflect light from the point light source toward the image carrier, and the reflecting member 1. An illumination device characterized in that an area between each illumination area on an image carrier that is directly illuminated by mutually adjacent point light sources is irradiated with reflected light from an adjacent point light source. (2) The illumination device according to claim 1, characterized in that a slit member is provided between the point light source and the image carrier in parallel to the direction in which the point light sources are arranged.
