Claims
- 1. A method of personalizing a core substrate of the type containing general authenticating information, said method comprising the steps of:
- (a) electrophotographically forming an electrostatic image of a visually identifiable personal feature on a photoconductive surface of an imaging member;
- (b) liquid developing said electrostatic image with toner particles in the size range from about 0.1 micron to about 1.0 micron; and
- (c) thermally transferring said developed toner image directly from said photoconductive surface to such a core substrate, said transferring step comprises passing the imaging member and such core substrate between the nip of a pair of transfer rollers with the toner image contacting the transfer member, the roller contacting said photoconductor being heated to a temperature greater than about 40.degree. C. and the roller contacting said core substrate being unheated.
- 2. The invention defined in claim 1 wherein said rollers are urged toward each other to provide nip pressure therebetween.
- 3. The invention defined in claim 1 further including the steps of separating the core substrate from said imaging member and laminating a transparent cover sheet over the toner image on said core substrate.
