Abstract

PURPOSE: To carry out improved magnetic cleaning without undergoing electrostatic induction or the like, by applying bias voltage or the like to keep a recorder surface and a magnetic cleaner same in potential.
CONSTITUTION: Bias voltage is applied to magnetic roller 2 with bias application device 4 in accordance with the surface potential detected of photosensitive drum 1, resulting in rendering the surfaces of drum 1 and roller 2 same in potential, eliminating the electric field between drum 1 and roller 2, and not causing electrostatic induction. Therefore, excess magnetic toner 3... undergoes improved cleaning unaffected by electrostatic induction by virtue of roller 2.
