Abstract
The present invention provides an electrophotographic lamination film which can be easily laminated by using the film as it is without significantly modifying a conventional electrophotographic device, can be printed with letters of high resolution directly on a surface of the film capable of softening at relatively low temperatures, and can form an image of high quality having sufficient heat resistance and light resistance with good recognizability even in outdoor use, as well as a method of producing the same and a method of forming an image. In the electrophotographic lamination film, a surface resistance of at least one surface of a substrate thereof is in a range of 108 to 1013 Ω/□, and a Vicat softening temperature of the substrate is in a range of 70 to 130° C.
