<p>PROBLEM TO BE SOLVED: To achieve both cleaning performance and magnetic particle leakage prevention over the entire longitudinal area in toner cleaning using magnetic particles.SOLUTION: There is provided a cleaning device that includes a magnet installed on the rear side of a toner carrying surface of an image carrier to hold magnetic material aggregate on the toner carrying surface, and a roller-like magnetic field generation member that is provided at a position downstream in the direction of movement of the surface of the image carrier with respect to the magnet. The magnetic field generation member can be rotated in the counter direction with respect to the direction of movement of the image carrier, and the surface of the magnetic field generation member has a surface shape having surface conveyability in a direction parallel to the rotation axis due to its rotation.</p> |
