Abstract

Disclosed is a liquid toner dispersion which has a relative low shear viscosity between 1.25 and 225 and a relative conductivity between 0.3 and 30. The liquid toner dispersion includes toner particles in a non-polar carrier liquid, as well as a dispersing agent. This liquid toner dispersion is used in a digital printing process including adding dispersing agent during recycling of excess liquid toner dispersion remaining on a development member after patterned transfer of liquid toner dispersion to the imaging member.
