Abstract
Method and apparatus for producing a hardcopy reproduction of image information. A uniform layer of toner particles is applied to a surface. A receiver sheet with a thermoplastic outer layer is placed over the layer of toner particles, the thermoplastic layer contacting the layer of toner particles. An electrostatic attraction is established between the layer of toner particles and the receiver sheet. The thermoplastic layer is imagewise exposed to heat to selectively soften the thermoplastic layer, allowing the toner particles opposite the softened thermoplastic to migrate into the layer. The receiver sheet is then removed from the surface, taking with it the migrated particles in an imagewise pattern.
