ABSTRACT:
A liquid image developing system includes a development container to store a developer; a photosensitive body; a development roller partially soaked in the developer in the development container and to rotate opposite to the photosensitive body; a metering blade to scratch the developer attached to a circumference of the development roller to a predetermined thickness; a depositing plate spaced from the development roller to form a space therebetween; a supplying portion to supply the developer to the space between the development roller and the depositing plate; and a power supply to apply a voltage to the depositing plate so that the developer is transferred to the development roller from the space by an electric force. 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.
