11249435 · 2022-02-15 · ·

An example cleaning station for a liquid electrophotographic printer is described. The cleaning station has a first cleaning member, a second cleaning member, and a biasing member. The cleaning station is configured to move between a first position and a second position with respect to a photo imaging member of the printer. In the first position, the first cleaning member is arranged to remove particles from the photo imaging member of the printer and the second cleaning member is arranged to apply a force to a layer of liquid applied to the photo imaging member. In the second position, the biasing member is configured to cause the second cleaning member to contact the first cleaning member to clean the second cleaning member.

PRINTER HEATING UNITS

A method is disclosed. The method may comprise applying a coating of electrically charged fluid print agent to a developer surface, the fluid print agent comprising particles of thermoplastic resin in a carrier fluid. The method may further comprise controlling migration of fluid print agent from the developer surface to form an image from fluid print agent on a first surface. The method may further comprise irradiating the print agent on the first surface with ultraviolet radiation to heat the print agent to a temperature of at least 70° C. to melt the thermoplastic resin. A print system and a heating unit are also disclosed.

Image formation with image-receiving holder and image formation medium

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.

Oil removing device and image forming apparatus

An oil removing device includes a first heating member that at an outer surface thereof contacts a non-image surface of a recording medium which is transported, and that heats the recording medium, a toner image that is formed by using liquid developer that contains volatile oil and toner being transferred to the recording medium; and a second heating member that is disposed on a downstream side of the first heating member in a transport direction, the second heating member contacting at an outer surface thereof the non-image surface of the recording medium and heating the recording medium. In the oil removing device, a non-contact region where the non-image surface of the recording medium does not contact the first heating member and the second heating member is provided between the first heating member and the second heating member.
