Abstract
Electrophotographic carrier compositions comprising a coating containing a resin and a mixture of positive and negative charge agents, and methods for making such carriers; and electrophotographic developers containing the same are disclosed.
Claims16
An electrophotographic carrier composition, comprising carrier particles comprising a core and a coating thereupon, said coating comprising a resin and a mixture of positive and negative charge agents.
An electrophotographic developer composition, comprising carrier particles comprising a core and a coating thereupon, said coating comprising a resin and a mixture of positive and negative charge agents;
- and toner particles.
A method of adjusting the triboelectric characteristics of a carrier composition containing a core and a resin-containing coating, comprising the step of preparing a coating material for application to metal core particles comprising resin and positive and negative charge agents, wherein said ratio of said positive and negative charge agents is effective to impart a desired net charge to said carrier particles, and the step of applying said coating material to a metal core.
