    摘要: An image forming apparatus comprising an image bearing member, a transfer material support member, fixing means and oil removing means for removing the oil deposited to the transfer material support member.The image forming apparatus selects either a first mode in which, after the fixation of the image by the fixing means on a first face of the transfer material, the transfer material bearing the fixed image on the first face is automatically supported on the transfer material support member to transfer an image of the image bearing member to a second face different from the first face of the transfer material, or a second mode in which, after the fixation of the image by the fixing means on a first face of a manually inserted transfer material, the transfer material is discharged from the apparatus without image formation on a second face different from the first face of the transfer material. In case of selection of the first mode, the oil removing means do not effect the oil removal after the transfer of the image of the image bearing member to the first face of the transfer material but effects the oil removal after the transfer of the image of the image bearing member to the second face of the transfer material, while, in case of selection of the second mode, the oil removing means effects the oil removal after the transfer of the image of the image bearing member to the transfer material regardless whether the manually inserted transfer material has passed the fixing means.

    摘要: An image forming apparatus includes an image bearing member for bearing an image, a rotatable recording material bearing member for bearing a recording material and conveying the recording material to a transfer station, the image formed on the image bearing member being transferred onto the recording material born on the recording material bearing member at the transfer station, and a cleaning means capable of being contacted with a surface of the recording material bearing member to clean the surface of the recording material bearing member at a cleaning station. When a length (L1) of a recording material born on the recording material bearing member in a rotational direction of the recording material bearing member is greater than a distance (L2) from the transfer station to the cleaning station along the rotational direction of the recording material bearing member, after the image is transferred onto the recording material born on the recording material bearing member, the recording material is conveyed to the transfer station again.
