Abstract
Abstract A xerographic marking apparatus including a charge receptor member (10), means (12) for creating an electrostatic latent image on the charge receptor member (10), means (16, 26) for developing the electrostatic latent image for making it visible, and means (32) for transfering and fixing the visible image onto a transfer sheet (30). The means for developing comprises first means (16) for electrostatically depositing a colorless adhesive developer material upon the electrostatic latent image, and second means (26a, 26b, 26c, 26d) for coloring the colorless adhesive developer material. <IMAGE>
