Abstract
A printing machine in which two electrostatic latent images are recorded on a photoconductive member. One of the latent images is a charged area latent image with the other image being a discharged area latent image. A magnetic developer unit develops the charged area latent image with black toner particles. A non-magnetic developer unit develops the discharged area latent image with toner particles of a color other than black. The toner particles from both latent images are transferred substantially simultaneously to a sheet and fused thereto forming a color high lighted document.
