In an image forming apparatus, at least a part of a cleaning roller is provided on the same side as an opposed roller with respect to an external common tangent Z of a first roller and a second roller. In a case in which a surface velocity of the driving roller is designated as v1; a surface velocity of the cleaning roller is designated as v2; a radius of the cleaning roller is designated as r; a radius of the opposed roller is designated as s; and a distance between the center of rotation of the cleaning roller and the center of rotation of the opposed roller is designated as x, the cleaning roller is rotated so as to satisfy a relationship: v2/v1
