LIQUID DEVELOPING ELECTROPHOTOGRAPHIC DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain an image having high image quality by forming an oil layer whose solid component concentration is low on the surface layer of a toner layer on a developing roller and then performing development while bringing the toner layer into contact with an image supporting body in the case of adopting constitution using a high-viscosity and highconcentration liquid toner. SOLUTION: This device is provided with a means for carrying and applying the liquid toner on the developing roller in a uniform thin layer state, and a conductive blade coming into contact with a liquid toner layer on the developing roller. The specified amount of liquid toner is made to pass between the conductive blade and the developing roller and also voltage is applied to the conductive blade, so that a condition that toner particles included in the liquid toner become sparse is formed on the surface of a uniform and thin toner layer on the developing roller. Thereafter, the development is performed while the liquid toner on whose surface the condition that the toner particles become sparse is formed is brought into contact with the image supporting body.
