Abstract

a. L'invention concerne un dispositif à flash pour fixer par voie thermique une image de toner réalisée sur des supports de copie. b. Il comporte un dispositif de commande du retard de phase 20 actionnant un interrupteur électronique de puissance 3 pour contrôler le courant de charge pour le condensateur 8, 9 du tube à flash 12, ainsi qu'un dispositif 21, 22, 23 pour faire varier l'angle de retard de phase en fonction de la tension momentanée du condensateur. c. Application aux appareils de reprographie par voie électrophotographique.
