<P>PROBLEM TO BE SOLVED: To provide an image formation device free to miniaturize requiring no large space to remove paper dust and to carry and collect the paper dust. <P>SOLUTION: A register roller part 600 includes a urethane rubber roller 610 and a tube roller 620 to nip recording paper S and a spiral roller 630 around which a spiral polyurethane foam making contact with the tube roller 620 is wrapped. An end surface of spiral teeth of the spiral roller 630 makes contact with the tube roller 620 and is frictional-electrified reversely to electrified polarity of the paper dust. A shaft and a side surface of the spiral teeth of the spiral roller 630 do not attract the electrified paper dust as they are electrically conductive and earthed, but carry the paper dust by rotating motion and spiral shapes. <P>COPYRIGHT: (C)2010,JPO&INPIT |
