Abstract

PURPOSE:To eliminate the defect of conventional cleaning equipment and to improve cleaning efficiency, by fixedly arranging two non-magnetic sleeves having a rotatable magnet roll in the inside near the electrostatic latent image carrier. CONSTITUTION:A drum 1 on which transfer is completed rotates along the direction of the arrow, and when remaining toner 9 which has not been transferred which adhere on the surface of the drum, comes near a fixed nonmagnetic sleeve 11 incorporating magnet roll 10, a part of the toner is adsorbed to the nonmagnetic sleeve due to the magnetic attracting force of the magnet roll 10. However, most of the remaining toner 9 on the drum 1 is not removed by only the magnetic force of the magnet roll 10, and the remaining toner reaches the contact point of an elastic roll 15 whose elastic body is fixed to a shaft 14. Then, the remaining toner 9 which has not been transferred is mostly removed by the elastic roll 15, and thus the cleaning efficiency is improved as compared to conventional equipment.
