ABSTRACT:
A liquid spreading device for spreading liquid over a target surface to be moved relatively to the liquid spreading device in a predetermined direction, including: a regulating member which is brought into contact with the target surface through the liquid; and a voltage applying unit for applying an electrical bias voltage across the regulating member and the target surface.
A fixing device for fixing a toner image onto an image bearing surface of a recording sheet, including: a rotating member having an outer surface to be in contact with the image bearing surface; a regulating member which is brought into contact with the outer surface of the rotating member through the liquid; and a voltage applying unit for applying an electrical bias voltage across the regulating member and the outer surface of the rotating member.
A fixing device including: a rotating member having an outer surface to be in contact with the image bearing surface; a spreading roller which is provided for spreading liquid over the outer surface of the rotating member and has an outer surface in contact with the outer surface of the rotating member; a regulating member which is brought into contact with the outer surface of the spreading roller through the liquid; and a voltage applying unit for applying an electrical bias voltage across the regulating member and the outer surface of the spreading roller.
