Abstract
Toner compositions comprised of a toner resin, a colorant, or pigment and an alkyl morpholinium compound of the following formula: ##STR1## wherein R.sub.1 is a hydrocarbon radical containing from about 8 to about 22 carbon atoms, R.sub.2 is hydrogen or a hydrocarbon radical containing from 1 to about 20 carbon atoms and A is an anion which in a preferred embodiment is selected from halides such as chloride, bromide, or iodide, sulphate, sulphonate, phosphate or nitrate.
Claims9
A method of imaging comprising forming an electrostatic latent image on a photoreceptor, which photoreceptor has been charged negatively, followed by contacting the image so formed with a developer composition comprising a resin material selected from a styrene butyl methacrylate resin, or a styrene butadiene resin, carbon black, a carrier material consisting of a steel core coated with a polyvinylidene fluoride resin, and a charge control additive selected from N-lauryl N-methyl morpholinium bromide, N-lauryl N-methyl morpholinium chloride, N-cetyl N-methyl morpholinium chloride, N-lauryl N-ethyl morpholinium chloride, or or N-cetyl N-ethyl morpholinium bromide, followed by subsequently transferring the developed latent image to a substrate, and permanently affixing the image thereto.
