ABSTRACT:
In an image forming apparatus, a developing device includes a reservoir storing a viscous and dense developing liquid. A developing sleeve, an applicator roller, a circulation pump for circulating the liquid and a screw for agitating the liquid are disposed in the reservoir. The reservoir is open only at its portion where the developing sleeve contacts an image carrier. The liquid is agitated by the screw before flowing into the circulation pump and then applied to the applicator roller. As a result, the liquid is fed to the developing sleeve via the applicator roller with a uniform toner content. The apparatus is small size and stably forms high quality images.
