Abstract
An electrostatographic printing apparatus is provided that is adapted for single-pass sequential multi-color duplex printing wherein the printing involves deposition and fixation of toner particles on a web-type final substrate. The apparatus includes: a first printing system having a first guiding member; a second printing system having a second guiding member, the printing systems being arranged in succession at opposite sides of the final substrate; an apparatus for rotating the guiding members and conveying the final substrate; an apparatus in each of the printing systems for superimposing color separation images in registration on the final substrate, wherein the color separation images are toner images including the toner particles; and an apparatus located between the first and second printing systems for reversing the charge polarity of the toner particles deposited onto the final substrate in the first printing system when the toner particles in the printing systems have the same charge polarity.
