Abstract

Appareil à développer uniformément une surface collante de définition d'image au moyen de matière en particules, comportant un distributeur 20 permettant de répartir une matière en particules au-dessus de ladite surface, un applicateur 22 permettant d'enchasser ou enrober la matière en particules dans la surface, un nettoyeur 24 permettant d'enlever de la surface l'excès de matière en particules, et des moyens 10, 12, 10', 12' permettant de déplacer la surface collante dans un sens devant le distributeur, l'applicateur et le nettoyeur. Le distributeur comprend une trémie 26 munie d'une paroi latérale mobile 28 indépendante et un dispositif 30 est prévu pour faire osciller cette paroi transversalement par rapport au sens mentionné, de manière à fournir la matière en particules 34 à la surface avec un débit réglé et uniforme Application, notamment, à l'électrophotographie.
