Abstract

Coated carrier compositions having varied triboelectric charging properties, in conjunction with a toner material, which are useful in the development of electrostatic latent images may be provided from epoxy resins, When an epoxy resin has been cured with aromatic anhydride the carrier material may be employed for reversal development, When an a2iphatic anhydride is used, the carrier material may be employed for either reversal or slightly positive develop-~ ment, When the epoxy resin is cured with an amine the carrier material may be employed for strongly positive development,
