ABSTRACT:
An apparatus for creating multiple color images is disclosed. The apparatus includes a charge retentive surface having a voltage saturation level, a plurality of imaging devices, and a plurality of developing devices. A first imaging device records a latent image on the charge retentive surface at a first exposure level. The latent image is then developed with a layer of toner particles by a first developing device. A second imaging device records a second latent image at a second exposure level. The second exposure level is a function of the voltage saturation level for the charge retentive surface and the maximum mass of the first layer of toner particles. A second developing device develops the second latent image with a second layer of toner particles and a third imaging device records a third latent image at a third exposure level. The third exposure level is a function of the voltage saturation level for the charge retentive surface, the maximum mass of the first layer of the toner particles, and the maximum mass of the second layer of the toner particles. A third developing device develops the third latent image with a third layer of toner particles.
