(EN) IMAGE FORMING APPARATUS AND METHOD FOR IMAGE FORMING
(FR) APPAREIL DE FORMATION D'IMAGE ET PROCÉDÉ DE FORMATION D'IMAGE
Abstract
(EN)
An image forming apparatus is provided. The image forming apparatus includes a sensor configured to sense a toner concentration, a processor configured to determine at least one of a coring level and a total area coverage (TAC) level according to the detected toner concentration, and an image former configured to print the rendered print data.
(FR)
L'invention concerne un appareil de formation d'image. L'appareil de formation d'image comprend un capteur configuré pour détecter une concentration de toner, un processeur configuré pour déterminer au moins l'un d'un niveau de carottage et d'un niveau de couverture de surface totale (TAC) en fonction de la concentration de toner détectée, et un dispositif de formation d'image configuré pour imprimer les données d'impression rendues.
