ABSTRACT:
The present invention provides a photosensitive body and an electrophotographic printer capable of notifying an operating whether a protection film 15 is correctly peeled off from a photosensitive surface 1a of the photosensitive body. The protection film 15 has marks 15a and 15b to be automatically detected. The electrophotographic printer 100 comprises a peel member 13, a guide route for guiding the peeled off protection film out of the printer, a magnetic sensor 14 for detecting the marks 15a and 15b, and a control circuit 17 for deciding according to an output of the magnetic sensor whether the protection film is correctly peeled off and outputting the decision result through a liquid crystal display panel 19. This enables an operator to know about the peeling state.
