Abstract
An electrostatographic imaging process includes forming an electrostatic latent image on an image forming device, developing the electrostatic latent image on the image forming device with at least one developer containing carrier particles and a blend of two or more compatible toner compositions, and transferring the toner image to a receiving substrate and fixing it thereto. Among the compatible toner compositions that may be selected are toner compositions having blend compatibility components coated on an external surface of the toner particles and particulate toner compositions containing therein blend compatibility components or passivated pigments. Electrostatographic imaging devices, including a tri-level imaging device and a hybrid scavengeless development imaging device, are also provided for carrying out the described process. The processes and apparatus of the present invention are especially useful in imaging processes for producing single color or highlight color images using customer selectable colors, or for adding highlight color to a process color image produced by the same apparatus.
