Abstract
An image-forming method and an image-forming transparent film are provided which can form a high-grade transparent recorded image such that any unwanted opaque matter other than images formed is not present on the transparent film on which the images have been formed. The transparent film is provided on its surface with an opaque sensing mark layer capable of turning transparent upon heating with a fixing roller and an opaque mark layer capable of turning transparent upon that heating. The opaque mark layer is capable of more readily turning transparent upon heating than the opaque sensing mark layer and is formed on the side upstream in the film transport direction from the position coming after substantially one rotation of the fixing roller, measured from an end of the transparent film in its transport direction, and the opaque sensing mark layer is formed on the downstream side of the opaque mark layer.
