Abstract : The objective of this project was to develop practical methods of manufacturing electrophotographic imaging materials namely, paper and toners for use on map printers. Electrophotographic paper sheet was successfully manufactured by the trailing blade technique. Development of liquid toners included testing a number of commercially available inks, but these were found to be unsatisfactory. Serious difficulties with electrically conductive contaminates, charge stability, squeegee ability, sedimentation, and other factors needed to be overcome. To correct these problems positive and negative toners and developers were specially formulated, produced in pilot plant quantities, and tested. The imaging materials, were satisfactory for use on the single color engineering test model map printer and the five-color map printer developed concurrently under the same contract. (Author)
