摘要:
An electrophotographic device is provided with a photosensitive drum having a plurality of photosensitive layers which are different from one another in spectral sensitivity. First and second uniform exposure devices are adjacent to each other about the photosensitive drum. Each of the first and second uniform exposure devices includes a plurality of single color light sources. The light sources of the first exposure device have a different color than the light sources of the second exposure device. The colors correspond to the spectral sensitivity of each of the photosensitive layers, and are used as the uniform exposure light source for the photosensitive drum.
