1. A device comprising:
a supply to supply an image formation medium along a travel path, wherein the image formation medium is non-absorptive and electrically conductive, and wherein a ground element is to be electrically connected to the image formation medium;
a first portion along the travel path to receive droplets of ink particles and a non-aqueous finishing 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;
a second portion downstream from the first portion to apply, via heat and pressure, a second polymer structure onto the ink particles, the finishing resin, and the image formation medium to produce an image formation medium assembly; and
a third portion upstream from the first portion to receive an electrically charged, semi-liquid image-receiving holder onto the image formation medium, wherein the image-receiving holder comprises a binder material and the droplets are substantially binder-material-free, and wherein the image-receiving holder comprises at least a portion of a first polymer structure on the image formation medium to receive the droplets.
 
8. A device comprising:
a control portion;
a media supply to supply an image formation medium along a travel path, wherein the image formation medium is non-absorptive and electrically conductive, and wherein a ground element is to be electrically connected to the image formation medium; and
a series of stations arranged along the travel path of the image formation medium in which each station is to provide one color ink of a plurality of different color inks onto the image formation medium, wherein each station comprises:
a first portion in which the control portion is to cause a fluid ejection device to deliver droplets of ink particles and a non-aqueous peel-strength-increasing 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; and
a second portion downstream along the travel path from the second portion and including a charge generation portion to emit airborne charges to charge the ink particles, via attraction relative to the grounded media, to move through the carrier fluid toward the image formation medium to become electrostatically fixed relative to the image formation medium; and
a station to apply heat and pressure to secure a second polymer structure to the ink particles, the non-aqueous, peel-strength-increasing resin, the first polymer structure, and the image formation medium to produce a medium assembly comprising the formed image.
 
11. A method comprising:
applying an electrically charged, semi-liquid image-receiving holder on an image formation medium moving along a travel path, including forming the image-receiving holder to include a binder, wherein the image formation medium is grounded and metallic;
after applying the image-receiving holder, selectively depositing, via a fluid ejection device, droplets of ink particles and resin within a dielectric, non-aqueous carrier fluid onto a first polymer structure on the image formation medium moving along travel path, to form at least a portion of an image, wherein the selectively deposited droplets are substantially binder free other than the resin, and wherein the image-receiving holder comprises at least a portion of the first polymer structure;
directing charges onto the ink particles within the deposited carrier fluid on the image formation medium to induce movement of the charged ink particles, via attraction relative to the image formation medium, through the deposited carrier fluid to electrostatically fix the charged ink particles in contact relative to the image formation medium; and
applying, via heat and pressure, a second polymer structure onto the charged ink particles, the resin, the first polymer structure, and the image formation medium to produce a medium assembly comprising the formed image.
