Abstract

An image forming apparatus including a black developer with increased capacity. The image forming apparatus includes optical scanners, where the optical scanners have the same focusing distance from the light source to the photo conductor, and the light reflecting unit of one of the optical scanners is arranged at a position different from the light reflecting unit of another optical scanner, such that intervals between the developers vary. Accordingly, although developers of the same type are used, the capacity of the black developer, which is most frequently used, may be easily increased by arranging the relative positions of the developers.
