Title
(EN) ELECTROPHOTOGRAPHIC LUMINESCENT AMPLIFICATION PROCESS
(FR) PROCEDE D'AMPLIFICATION ELECTROPHOTOGRAPHIQUE PAR LUMINESCENCE
Abstract
(EN)
An electrographic luminescent amplification process is described which includes the steps of: (a) forming a low amplitude differential voltage pattern on a photoconductor; (b) developing the low amplitude differential voltage pattern with a luminescent toner to form a luminescent toner image; (c) exciting the luminescent toner image to produce emitted radiation; (d) exposing a photoconductor to the emitted radiation to produce a high amplitude differential voltage pattern on the photoconductor; and (e) developing the high amplitude differential voltage pattern to produce a high density image.
(FR)
Un procédé d'amplification électrographique par luminescence comprend les étapes suivantes: (a) la formation d'un motif de tensions différentielles de faible amplitude sur un photoconducteur; (b) le développement du motif de tensions différentielles de faible amplitude avec un toner luminescent afin de former une image luminescente avec le toner; (c) l'exposition du photoconducteur aux rayonnements émis afin de produire un motif de tensions différentielles de forte amplitude sur le photoconducteur; et (e) le développement du motif de tensions différentielles de forte amplitude afin de produire une image de haute densité.
