になってきた。Polymer compound films such as polyester, polyvinyl chloride, polystyrene, polyimide, polyethylene, polypropylene, polycarbonate, acetate, etc. are used as overhead projector (OHP) films in electrostatic transfer copying machines and magnetic transfer copying machines. There is a transparent film that has been subjected to conductive treatment, but due to the recent demands for higher speed and higher reliability of copying machines, it is necessary to set the paper feed timing,
As more and more copiers are switching from conventional mechanical detection methods (e.g. microswitches) to optical detection methods (e.g. photocouplers) to detect paper jams, conventional transparent films can no longer detect paper jams. When used in a copying machine, problems such as frequent paper jams due to poor paper feed timing and troubles associated with the inability to stop the copying machine when paper jams occur have become a problem.

In order to make effective use of the entire surface of the film when used in an overhead projector, a material with high light transmittance in the visible region and low light transmittance in the near-infrared region is placed on the surface of the metal edge. The present invention provides a transparent film for electrophotography.

Ｘ〜５０Ｘが望ましいことがわかる。From these results, when gold is vapor-deposited on the edge surface of the film, in order to make the light transmittance at 500 nm wavelength 70% or more and the light transmittance at 950 nm wavelength 40% or less, It is understood that the thickness must be 100X or less. However, the running properties of the film decrease as the thickness of the deposited layer decreases, and the visibility of images when using an OHP deteriorates as the thickness of the deposited layer decreases. Therefore, considering the three factors of light transmittance, film runnability, and image visibility, the thickness when the vapor deposition material is gold is 100 mm.
It can be seen that X to 50X is desirable.
