PROBLEM TO BE SOLVED: To prevent image deterioration such as the void of an image, an disfigured image, etc., by preventing the adhesion of a substance which deteriorates surface resistivity by giving an insulating liquid to a latent image carrier surface. SOLUTION: If the accumulated print number of sheets exceeds a specified value inputted in advance, the oscillation means of a coating roller 31 is driven to move the coating roller to a position where the coating roller abuts on a photoreceptor 11. The insulating liquid is already coated on the coating roller by a coating member, and a minute amount of insulating liquid is coated on a photoreceptor surface from the coating roller by the normal rotation of the photoreceptor surface in this state. |
