摘要： A liquid developer imaging system and a method using the system for developing an image, including a cartridge for containing a developing solution; a developing container for receiving the developing solution supplied from the cartridge via a predetermined supply line; a developing roller partly submerged in the developing solution contained in the developing container, installed to be rotated facing a photosensitive object; and a metering blade for scraping off the developing solution coated on the surface of the developing roller to a predetermined thickness, is provided. According to the system, a developing supply structure can be considerably simplified because a high-density developing solution is directly used in developing an image without a process of diluting the solution, and an image can be developed to have high definition because the concentration of the developing solution coated on the developing roller is regularly controlled by a metering blade.
