PURPOSE:To prevent the defect of an image from occurring because releasing agent used at the time of fixing toner adheres to a photosensitive drum through a recording material. CONSTITUTION:A recording material carrying sheet 11 is stretched and attached to a base member 10 obtained by coupling cylinder parts 10a and 10b through a coupling part 10c. Many groove-state minute recessed parts 11a are formed in a rotating direction R2 on the surface of the sheet 11, so that the surface is made rough. In the case of both-side copying, the releasing agent (oil) used at the time of fixing the toner on the first side adheres to the surface of the sheet 11 from the recording material and further adheres to the photosensitive drum from the surface of the sheet 11 at the time of copying the next side. Since the contact area of the recording material and the sheet 11 is made small by the recessed parts 11a, the transferable adhesion of the releasing agent to the sheet 11 is reduced. Furthermore, the releasing agent gets into the recessed parts 11a, thereby reducing the transferable adhesion of the releasing agent to the photosensitive drum. |
