Title (EN) COLOR ELECTROSTATIC RECORDING APPARATUS
(FR) APPAREIL D'IMPRESSION ELECTROSTATIQUE EN COULEUR
Abstract:
(EN) A single-pass color electrostatic recording apparatus including an electrostatic recording head for forming an electrostatic latent image on a recording medium advancing in sliding contact with it, a development unit paired with the recording head for developing the electrostatic latent image, and a unit for adjusting the sliding contact of the recording medium with the electrostatic recording head, wherein the electrostatic recording heads and the development unit are provided in the necessary number for color image recording, each electrostatic recording head has a greater radius of curvature on the surface thereof on the upstream side than on the downstream side in the moving direction of the recording medium, and the sliding contact adjustment unit can easily adjust the pressure at the center of the electrostatic head in accordance with the kind of the recording medium.
(FR) L'invention concerne un appareil d'impression électrostatique couleur à un seul passage, comportant une tête d'impression électrostatique conçue pour former une image électrostatique latente sur un support d'impression avançant en contact glissant avec celle-ci, un organe de développement, apparié à la tête d'impression et conçu pour ajuster le contact glissant du support d'impression avec la tête d'impression électrostatique, les têtes et l'organe de développement étant fournis en nombre suffisant pour permettre une impression d'image en couleur. Par ailleurs, la surface de chaque tête d'impression électrostatique présente un rayon de courbure supérieur du côté amont que du côté aval, dans le sens de déplacement du support d'impression, et l'organe d'ajustement du contact glissant peut ajuster facilement la pression au centre de ladite tête en fonction du type de support d'enregistrement.
