Separator device for transfer medium

摘要

This specification discloses improvements in a separating belt disposed between an image-bearing member such as a photosensitive medium or the like and a transfer medium to which the image on the image-bearing member is to be transferred. In the device of the prior art, the separating belt has been fatigued by being subjected to localized friction with respect to the image-bearing member and/or a rotating member for effecting the separation. In the present invention, the separating belt is gradually moved in accordance with the operation of the device incorporating the separating belt therein, whereby the separating belt may be prevented from localized friction and need not be replaced by another belt for a long time.
