PURPOSE:To prolong the service life of a photosensitive film by constituting the photosensitive film into 'Mobius strip shape'. CONSTITUTION:The photosensitive film 1 is constituted into a 'Mobius strip', and both sides are uniformly used. That is, the photosensitive film 1, constituted into the Mobius strip, is attached to rollers 4. A cleaner 2 is assembled so as to pinch the photosensitive film 1. An EP system 3 is positioned between the rollers 4. Therefore, physical and electrical stresses, such as electrification, exposure, development, transfer, erasure, and cleaning, are applied to both the surfaces of the film 1. Thus, the service life of the film entire surface can be prolonged. |
