Abstract

Appareil de formation d'images comprenant une surface de formation d'images sur laquelle est formée une image révélée, et un organe de transfert intermédiaire (30, 102, 104) qui reçoit l'image révélée en provenance de la surface de formation d'images, ladite image étant ensuite transférée à partir dudit organe de transfert. L'organe de transfert intermédiaire (30, 102, 104) comprend un tambour (30) dans lequel sont formées des évidements de fixation, et un blanchet de transfert intermédiaire (104) monté sur le tambour (30). Ce blanchet (104) présente une zone de transfert stratifiée dont l'une des faces porte une surface de transfert (109) apte à recevoir l'image révélée, tandis que son autre face porte éventuellement une couche adhésive (126), ainsi qu'un élément de fixation (106) fixé à l'un des bords de la zone de transfert stratifiée et conçu pour coopérer avec les évidements de fixation ménagées dans le tambour, de sorte que le blanchet de transfert (104) soit monté solidaire et amovible sur le tambour (30).
