ABSTRACT:
In an apparatus in which a yellow, magenta, and cyan toner images are superimposed on a photoreceptor drum made of a transparent material, an image exposure device is provided in the photoreceptor drum and emits exposure lights whose wavelength has a spectral reflective ratio lower than 30% for at least two of yellow, magenta, and cyan toners. The image forming processes is controlled so that a toner image for which the exposure lights have a spectral reflective ratio larger than 30% is formed after toner images for which the exposure lights have a spectral reflective ratio lower than 30% have been formed.
