Abstract

Proposed is a system for forming and developing a toner image on a self supporting insulating film. The film may be transparent or opaque, but must be thin enough to permit charge deposition without blooming problems. The charges induced to the second surface of the insulating film must be applied as fast as those applied, in imagewise patterns, to the first side. Conversely, the latent image formed on the second side must be developed as fast as that on the first side. For ionography at 10 inch per second, 400 lines per inch, with 5 spots per aperture, each pixel must be written every 50 microseconds with a slit corotron. Alternatively, the charging process may be reduced to 1 inch per second, at 1 millisecond, with 3 spots per aperture.
