Abstract
An image forming apparatus includes a cleaning member which frictionally contacts magnetic particles on a magnet roller with an image bearing member in order to remove foreign matter adhered to the image bearing member, thereby preventing the deteriorating of the image quality. The magnet roller rotates slowly so that a portion thereof opposed to the image bearing member is moved in the same direction as a moving direction of the image bearing member. This prevents the toner from overflowing and scattering out of the cleaning member. Further, when non-magnetic toner is used, by providing a toner cavity on the magnet roller, the scattering of the non-magnetic toner can be prevented, whereby parts inside the apparatus are prevented from being contaminated by the toner.
