Liquid development apparatus, liquid development method, and image forming apparatus and image forming method using liquid development

摘要

A liquid development apparatus utilizes wet development as a development method and an image forming technique. The apparatus uses squeegee rollers, disposed facing a developer roller, and moved to adjacent positions at which the squeegee rollers contact a liquid developer which is on the developer roller. Density adjustment bias generators are connected between the developer roller and the squeegee rollers. The density adjustment bias generators include, among other things, positive bias power source parts, negative bias power source parts, short-circuit line parts, and switches which switch connections of the respective parts through in accordance with a control signal received from a CPU. A method that the apparatus performs is also provided.
