PROBLEM TO BE SOLVED: To detect whether a new photoreceptor is attached or not and the peeling action of a photoreceptor protection film and the ejecting action thereof from an electronic recorder are normally executed or not by providing the protection film with a part to be detected by a protection film detector arranged on the inside of the electronic recorder. SOLUTION: When the new photoreceptor 1 is attached to the recorder and a belt is driven to be fed, the leading edge of the protection film floating up from the surface of the photoreceptor 1 at the part of a belt guide roller (b4) is picked up by a protection film guide 13 positioned on a downstream side in the belt feeding direction of the roller (b4) so as to be guided to a press- contact part being a normal paper carrying path between a transfer roller 10 and a fixing roller 11. At this time, the part to be detected formed at the leading edge part of the protection film is detected by the protection film detector 14 arranged near the guide 13. Then, it is detected that the peeling action of the protection film from the photoreceptor 1 is started and the ejecting action thereof from the recorder is started. |
