摘要： A liquid electrophotographic developing device for developing a charged and exposed photoconductive material which includes a photoconductive layer formed on one surface of a conductive layer. The liquid electrophotographic developing device is comprised of developing section, a developing solution tank provided in a housing and filled with a developing solution, conveying rollers for conveying the photoconductive materials, a developing electrode and a back electrode which are disposed parallel along a conveying path of the photoconductive material in the developing section, and a developing solution supplying device disposed above the developing electrode. The developing electrode is spaced part from the photoconductive layer, and the back electrode is disposed to come into contact with the back surface of the photoconductive material. Upon directly connecting the electrodes, toner particles contained in the developing solution adhere to the photoconductive layer to achieve development. The developing electrode does not touch the photoconductive layer to make a developed image free from soiling. The housing is covered with a lid to prevent the vaporizing of the developing solution. The developing solution is circulated through the developing section by a circulating device.
