Abstract
A drive force transmission mechanism includes a drive pulley, a driven pulley and an endless belt. The endless belt is wound around the drive pulley and the driven pulley and transmits a rotation of the drive pulley to the driven pulley. At least one of the drive pulley and the driven pulley has a protruding part protruding outwardly in a radial direction around an outer circumferential face of the drive pulley or the driven pulley. The belt is a nonmagnetic metal belt having an outer circumferential face and an inner circumferential face. The outer circumferential face has a surface roughness smaller than a surface roughness of the inner circumferential face.
