Problems solved by technology

[0011] However, since the drying section 130 evaporates the liquid carrier remaining on the surface of the photosensitive belt 110 and then recovers it in a gaseous state, a large amount of liquid carrier cannot be fully removed, esp

Embodiment Construction

[0020] refer to figure 2 , The wet laser printer 300 according to the embodiment of the present invention includes a supporting roller 321 for supporting the photosensitive belt 310 , a regulating roller 322 and a driving roller 323 . The driving roller 323 drives the photosensitive belt 310, and the regulating roller 322 adjusts the tension of the photosensitive belt 310 to prevent the photosensitive belt 310 from deviating from its circular track.

[0021] The surface of the photosensitive belt 310 is uniformly charged by the main charger 335 . A laser scanning unit (LSU) 330 is installed on the downstream side of the photosensitive belt 310 to irradiate a laser beam on the photosensitive belt 310 according to an image signal to form an electrostatic latent image. The developing device 340 is used to apply a developing solution containing a mixture of toner of a predetermined color and a liquid carrier on the electrostatic latent image to develop it. In a color printer, a...

Abstract

A wet electrophotographic printer comprising: a photosensitive belt supported and run around by a set of rollers; a developing device for supplying a developer to the photosensitive belt; and a drying roller for removing a liquid carrier in the developer on the photosensitive belt. The drying roller includes a cylindrical roller body with a cavity and a through hole guiding the cavity, a rotating part that is rotatably mounted on the outer surface of the roller and has a group of mesh-shaped inlet holes; and an absorbing part that cooperates with the outer surface of the rotating part. to absorb the liquid carrier on the photosensitive belt; the wet electrophotographic printing machine also includes: a heating roller for evaporating the liquid carrier on the drying roller; and a collection box for recovering the evaporated liquid carrier.

Description

technical field [0001] The present invention relates to a wet electrophotographic printer, and more particularly to such a wet electrophotographic printer having a recovery means for recovering a liquid carrier from a dry roll in contact with a photoreceptor. Background technique [0002] Generally, in a wet electrophotographic printer such as a laser printer, an electrostatic latent image is formed on a photoreceptor such as a photosensitive drum or a photosensitive belt, developed with toner having a predetermined color, and transferred to paper, The desired image is thus obtained. [0003] Laser printers can be broadly classified into wet and dry types according to the toner used in them. Wet laser printers use a developer solution that contains toner mixed with a volatile liquid carrier. Wet laser printers show better image quality than dry laser printers. And wet presses prevent the hassle of using dangerous toner powders. As a result, the use of wet laser printers ...
