In the shift from monochrome to color multi function printers (MFPs) in recent years, demands for durability, reliability, and print quality continue to glow. In order to meet such demands, we have developed new technologies for a photoconductor unit equipped with a small particle size of polymerized toner. The technologies include a high-durable photoconductor reinforced with inorganic filler, the non-contact charging system with a hard roller, and a new cleaning system containing the function-separated lubricant application device. The technologies assure high reliability and a long lifetime under various conditions of usage and have been introduced to the imagio MP C4500/3500 series.
