Abstract
A latent color image developing system for copying a document having a first color images and second color images develops the first color images with a first color developer and the second color images with a second color developer. The second color developer includes a toner and a magnetic carrier having a density of less than 4.0 g/cm.sup.3 and a particle size in the range of 30-50 microns. A developer roll is used having a main developing pole with a flux density of more than 500 gauss in a nip region proximate a photosensitive member having latent electrostatic images to be developed.
