Abstract
A liquid image developing system, including a cartridge in which a developer is stored; a supply line; a development container to which the developer is supplied from the cartridge through the supply line; a photosensitive body in the development container; a development roller partially soaked in the developer in the development container and rotating opposite to the photosensitive body; a depositing member to create a potential difference required to attach the developer to a circumference of the development roller, opposite to the development roller; a metering blade to scratch the developer attached to the circumference of the development roller to a predetermined thickness; and an agitator to agitate the developer contained in the development container. Accordingly, a high-concentration developer can be directly used in the development operation without a dilution operation, and thus the structure to supply the developer can be considerably simplified.
