ABSTRACT:
An image forming apparatus having improved arrangement of photosensitive members and configuration of a light scanning device to enable size reduction is described. The image forming apparatus includes a plurality of photosensitive members, a light scanning device to irradiate light beams to the plurality of photosensitive members, so as to form electrostatic latent images on the photosensitive members, a plurality of developers to supply a developing agent to the photosensitive members, so as to form visible images on the photosensitive members, and a transfer drum disposed in contact with the photosensitive members and used to transfer the visible images such that the visible images overlap one another. Scanning lines, which are formed on the plurality of photosensitive members, respectively, by the light scanning device, are arranged in at least two different planes.
