Abstract

Copieur comprenant un photorécepteur, des moyens de formation d'une image latente électrostatique sur le photorécepteur, un applicateur tournant destiné à mettre en contact l'image latente avec du révélateur venant de la réserve et des moyens de distribution d'un complément de révélateur. Le copieur comporte des moyens 70, 174 propres engendrer un signal 77 indiquant le moment où la réserve de révélateur a besoin d'être reconstituée, des moyens 80 conçus pour exciter les moyens de distribution en réponse au signal d'indication et des moyens 36, 92, 94, 96 servant à empêcher le fonctionnement des moyens de distribution pendant un laps de temps prédéterminé après le début de la rotation de l'applicateur. Application à la reproduction des documents.
