Abstract
A developer unit for a wet-type color image forming apparatus. The developer unit includes a developer bath filled with a liquid developing agent to a predetermined depth, and a developing roller that develops an electrostatic latent image formed on a photoreceptor to correspond to an original image by supplying the liquid developing agent while being partially immersed in the liquid developing agent. The developer unit further includes a cleaning roller that cleans the surface of the developing roller, a depositing roller that deposits the liquid developing agent onto the cleaned surface of the developing roller, and a metering roller that adjusts the thickness and concentration of the liquid developing agent deposited onto the surface of the developing roller by the depositing roller to suitable levels to develop the electrostatic latent image. The developer unit also includes a developer cartridge that supplies the liquid developing agent into the developer bath.
