ABSTRACT:
A transparent film used as recording media in an electrophotographic apparatus and having different expansion and shrinkage characteristics during heating in length and width directions. At the end portion of the film in the direction in which the film has slighter shrinkage is provided a non-transparent member so that the passage of the film can be detected by means of photosensors without the non-transparent member being peeled away from the film due to the differences in the shrinkage factors of the film and the non-transparent member upon fixing.
An image forming method for forming an image on the transparent film. In the above method, the transparent film is set at a supply portion of the electrophotographic apparatus so as to be fed along the direction in which the film has greater shrinkage during heating, so that the film does not jam and roll up on a fixing rollers and is allowed stable image formation.
