Brush type cleaner

Abstract

Abstract PURPOSE:To prevent melt sticking of toners on flicker bars and maintain the electrostatic condition of cleaning brushes constant by constituting a cleaner in such a way that the flicker bars rotate freely when the bars contact with the cleaning brushes and the flicker bars are grounded. CONSTITUTION:When cleaning brushes 3, 4 rotate in arrow directions, the preceding ends thereof contact frictionally with the outside cylinders 8 of fricker bars 5, 6 respectively, and rotates the same in the arrow directions. The brushes 3, 4 are charged electrostatically in an adequate state by such frictional contact. The toners remaining on the surface of a photoreceptor 1 are thus removed and stick on the preceding ends of the brushes 3, 4. The brushes 3, 4 continue to rotate in the arrow directions further and contact again with the cylinders 8. The toners stuck on the ends of the brushes 3, 4 are scraped off in this stage. If the brushes 3, 4 rotate in the arrow directions, the cylinders 8 rotate in the arrow directions as well; therefore, the contact areas between the brushes 3, 4 and the bars 5, 6 are not constant all times and the toners are not melt stuck on the surfaces of the clyinders 8. The bars 5, 6 are kept free from accumulation of electric charge. The charging state of the brushes is thus maintained constant.
