摘要： The liquid toner dispersion comprises marking particles to which dispersing agent is bound for dispersing the marking particles in a substantially non-polar carrier liquid. The dispersing agent is of a hyper-dispersant type comprising an anchor group for binding to a marking particle and stabilizing groups coupled to the anchor group for stabilizing said marking particle in the carrier liquid. The dispersion further comprises a spacer agent that comprises a polar head group and a substantially non-polar tail, and that acts as a spacer of the marking particles.

摘要： The digital printing system comprises a development member in rotational contact with a further member for imagewise transferring liquid toner from the development member optionally via said further member to a substrate. The system is such that toner residue remains on the development member after the transfer. Treatment means are present for patternwise treatment of said toner residue on said development member, especially by addition of a dispersing agent, so as to facilitate removal of the toner residue by means of removal means. Control means are present for controlling the patternwise treatment. The system is used for robust and continuous printing and is suitable for recycling of the toner residue into liquid toner.
