<P>PROBLEM TO BE SOLVED: To favorably develop an electrostatic latent image of a photosensitive drum by a developing roller by forming a toner layer with uniform film thickness on the developing roller in a wet type developing device. <P>SOLUTION: An anilox roller is brought into rotational contact with a developing roller; and a doctor blade and a toner charger are disposed facing the anilox roller, and a corona charger for applying plus charge is disposed facing the developing roller in the upstream side of a rotational contact portion of the developing roller with a photosensitive roller, liquid developer with the viscosity of 5-80 mPa.s is used, and the toner layer with a film thickness of 3-4.8 μm is formed on the surface of the developing roller. <P>COPYRIGHT: (C)2012,JPO&INPIT |
