Provided is a toner transfer device including: a carrier device that includes a surface on which a charged toner is carried; an electrode that attracts the toner from the surface of the carrier device; a conveyance path of a print medium which is formed between the carrier device and the electrode; and a power supply device that causes a potential difference to occur between the carrier device and the electrode to transfer the toner from the carrier device onto the print medium when the print medium is located in the conveyance path.

An image formation device includes at least one frame portion supporting at least one emitter to emit airborne charges, at least one radiation element to emit radiation, and a fluid ejection device to deposit droplets of ink particles within a non-aqueous fluid carrier onto a substrate. Upon relative movement between the at least one frame portion and the substrate, the emitted airborne charges are to electrostatically fix, and the at least one radiation element is to emit radiation to cause at least further fixation of, the deposited particles relative to the substrate.

An image formation device includes a mixer, a fluid ejection device, and a liquid removal element. The mixer is to receive a first ink mixture of ink particles within a first non-aqueous liquid carrier in a first concentration, to receive a second non-aqueous liquid carrier, and to form a second ink mixture of the ink particles within both the first and second liquid carriers in a second concentration less than the first concentration. The fluid ejection device is to receive the second ink mixture and to deposit droplets of the second ink mixture onto a substrate to at least partially form an image via the ink particles. The liquid removal element is to remove the respective liquid carriers from the substrate to provide at least a portion of the second liquid carrier at the mixer to form part of the second ink mixture.

A scanning carriage of a printer includes a first emitter to emit first airborne charges, a second emitter to emit second airborne charges, and a fluid ejection device interposed between the first and second emitters to deposit droplets of ink particles within a non-aqueous fluid carrier onto a print medium to form an image. The carriage is movable relative to the print medium in a first direction and an opposite second direction. In the first direction, the first emitter is to electrostatically discharge the medium and the second emitter is to induce electrostatic fixation of the ink particles relative to the medium. In the opposite second direction, the second emitter is to electrostatically discharge the medium and the first emitter is to induce electrostatic fixation of the ink particles relative to the medium.

A device includes an image formation medium supply, a first portion, and a second portion. The image formation medium supply is to supply a non-absorptive, image formation medium along a travel path and to which a ground element is to be electrically connected. The first portion along the travel path is to receive droplets of ink particles and a non-aqueous resin within a dielectric, non-aqueous carrier fluid on the image formation medium to form at least a portion of an image on the image formation medium. The second portion is downstream from the first portion and is to apply, via heat and pressure, a second polymer structure onto the ink particles, the resin, and the image formation medium to produce an image formation medium assembly.
