Abstract
Printing methods are provided. In one method an inkjet image is printed using an ink having a colorant with an electrical charge of a first polarity dispersed in a hydrophilic liquid carrier fluid with an electrical charge of a second polarity that is the opposite polarity of the first polarity. A colorant attracting toner image conforming to the inkjet image is generated using toner particles of the second polarity. The colorant attracting toner image is transferred in registration with an unabsorbed volume of the ink jet image on the receiver. The difference in polarity between the toner particles and the colorant attracts the colorant and the toner particles. The toner particles are fixed to the receiver. After fixing colorant attracted to the toner particles is bound to the toner particles so that removal of the toner from the receiver also removes any colorant attached to the toner from the receiver.
