Claim One:
1. A latent image developer system comprising: (a) document platen; (b) vacuum container supporting said document platen; (c) vacuum generator; (d) positive platen plate charge generator; (e) negative charge generator; (f) developing wand; wherein said document platen is porous, permitting adhesion of a latent image document to the surface of said document platen when a vacuum is applied to the opposite side of said document platen; said document platen mates to said vacuum container to form an airtight interface; said vacuum generator produces a vacuum within said vacuum container; said positive platen charge generator permits application of a positive charge to said document platen and said latent image document when placed thereon; said negative charge generator permits application of a negative charge via said developing wand to said an insulating film placed upon said latent image document when said document is placed on the outer surface of said document platen; said negative charge applied to said insulating film permits attraction of an imaging powder to reveal latent images in said latent image document.
