Abstract
Toner development with conductive toner in electrophotography has been considered as an alternative to the most widely used dual-component toner development process. While in the latter case insulative toner particles are charged using tribo-electrification, this is not required for conductive toner where toner particles will be inductively charged when subjected to an image wise applied electrical field. Incorporating magnetic pigment in conductive toner particles allows for monocomponent development systems.
This paper describes theory, key characteristics, advantages and challenges of conductive toner development with monocomponent magnetic toner. It will also describe the application in Océ printing systems.
