Abstract
A developer cleaning method for a liquid electrophotographic printer is achieved by developing an electrostatic latent image by supplying developer supplied from an injection nozzle to a photoreceptor medium via a development roller, removing drip developer formed on the photoreceptor web between a squeegee roller and the development roller, removing developer remaining between the injection nozzle and the development roller, and reducing an electrical potential of the development roller after development so that toner particles included in the drip developer are transferred to the development roller due to a difference in electrical potential.
