cleaning equipment

Abstract

Abstract PURPOSE:To stabilize cleaning performance on every environmental condition by recovering residual toner which is caught on an image carrier by a conductive fur brush by a conductive recovery roll applied with a specific bias, and sweeping it off the roll. CONSTITUTION:The conductive fur brush 6 is applied with a bias which different in polarity from the electrostatic charging polarity of toner and is <=200V in absolute value from the 1st bias electrode 19. The conductive recovery roll 7, on the other hand, is applied with a bias which has the same polarity with the bias applied to the brush 6 and is 200-500V or more in absolute value from the 2nd bias electrode 24. Then, the fur brush 6 is formed by weaving brush elements in base cloth in a W shape, the resistance value during rotation is, for example, 10<6>-10<8>OMEGA, and the brush is grounded through a resistance having a less resistance value. Consequently, the cleaning performance is stabilized on every environmental condition.
