Abstract
An image forming apparatus includes a plurality of image forming units, each unit developing a latent image formed on a respective photosensitive drum with a respective color toner to form an image on a sheet of paper. The image forming apparatus includes an exposing optical device for projecting light on the photosensitive drums, a first movable mirror for reflecting the light along a first optical path and a second movable mirror for reflecting the light reflected from the first movable mirror to a selected photosensitive drum along a second optical path. The first and second movable mirrors move so that the optical path lengths are constant irrespective of the position of the selected photosensitive drum. Latent images, each having a uniform size, are formed on the photosensitive drums.
