TONER PARTICLES WITH MODIFIED CHARGEABILITY

摘要

A liquid toner for electrostatic imaging which includes: an insulating non-polar carrier liquid, at least one charge director and toner particles dispersed in the carrier liquid. The particles include a core material which is unchargeable or weakly chargeable by the at least one charge director, but which is otherwise suitable for use as a toner material and a coating of at least one ionomer component in an amount effective to impart enhanced chargeability to the ordinarily unchargeable or weakly chargeable particles.
