Claims
- 1. A method of imaging which comprises forming a negative electrostatic latent image on a photoresponsive imaging device, contacting the resulting image with a positively charged toner composition comprised of resin particles, pigment particles, and from about 0.1 percent by weight to about 10 percent by weight of a pyridinium tetrafluoroborate charge enhancing additive of the formula ##STR3## wherein R.sub.1 is an alkyl group containing from about 1 carbon atom to about 22 carbon atoms, followed by subsequently transferring the developed image to a suitable substrate, and permanently affixing the image thereto with a fuser roll containing lead oxide and a vinylidene fluoride hexafluoropropylene copolymer thereon.
- 2. A method of imaging in accordance with claim 1 wherein the photoresponsive device is comprised of a substrate, a photogenerating layer, and a charge transport layer.
- 3. A method of imaging in accordance with claim 2 wherein the photoregenerating layer is trigonal selenium or vanadyl phthalocyanine, dispersed in a resinous binder, and the charge transport layer is comprised of N,N'-diphenyl-N,N'-bis(3-methylphenyl)1,1'-biphenyl-4,4'-diamine dispersed in a polycarbonate resin.
- 4. A method of imaging in accordance with claim 1 wherein the resin particles are comprised of a styrene n-butyl methacrylate copolymer, a polyester or a styrene butadiene copolymer.
- 5. A method of imaging in accordance with claim 1 wherein the fuser roll is a soft fuser roll.
