An image formation device includes a transfer member and a first portion to receive an electrically charged, image-receiving holder onto the transfer member. A second portion downstream from the first portion is to receive droplets of ink particles within a dielectric carrier fluid onto the electrically charged, image-receiving holder to form at least part of an image. A charge source is to emit airborne charges to charge the ink particles to move, via attraction relative to the image-receiving holder, through the carrier fluid to become electrostatically fixed relative to the image-receiving holder. A liquid removal unit is to remove at least the carrier fluid from at least a surface of the image-receiving holder. A transfer station is to transfer the ink particles of the image and the image-receiving holder together from the transfer member to an image formation medium.
