ABSTRACT:
A copying machine having means for producing a fusible toner image on a copy substrate, includes a radiant energy light source (e.g. iodine quartz lamp) mounted to direct part of its rays onto the object that is to be copied to illuminate the latter, and part onto the surface of a rotating receiver roll to heat the surface thereof approximately to the fusing temperature of the toner. The copy substrate is passed beneath the receiver roll tangentially thereof by a transport which causes the toner image to engage the heated receiver surface with a minimal amount of pressure so that the toner is fused and fixed to the substrate. Various release agents may be applied to the roll surface to enhance fixing of the image; and various additives to the toner and/or the developer containing the toner, or to the substrate, may also be used to improve image transfer, image fixing, etc. Novel toners, carriers and photo-conductors for use in this copying process are also disclosed.
