The present application discloses an image formation apparatus that can transfer an image into electronic paper using an electronic photography method, and a printing control method for the image formation apparatus. The present electronic paper comprises an electrophoresis layer for displaying an image using an electrophoresis method, a conductive layer, and a film layer for transmitting an image; and the image formation apparatus comprises a communication interface for receiving printing data, an image formation unit for transferring an image corresponding to the printing data, and a processor for controlling the image formation unit.

Electronic paper, image formation apparatus, and printing control method

A fixing unit includes: a fixing member which defines a fixing nip, where the fixing member fixes a toner image transferred onto a recording medium by applying heat and pressure to the toner image on the recording medium, and the recording medium passes through the fixing nip; a housing in which the fixing member is disposed, where the housing includes an entrance part, via which the recording medium enters therein, and a discharge part, via which the recording medium is discharged therefrom; and a blocking part disposed on the housing and toward an image surface of the recording medium to which the toner image is transferred, where the blocking part blocks nanodusts, which are generated while the toner image is being fixed to the recording medium, from being discharged to an outside of the housing.

Fixing unit and image forming apparatus including the same

An image forming apparatus includes a developing module which develops a toner image on a printing medium, a fixing module which fixes the toner image onto the printing medium, and a toner neutralization module arranged on a travel path of the printing medium between the developing module and the fixing module to electrically neutralize the toner image on the printing medium.

Image forming apparatus

An encapsulated colorant including a colorant and a polymer resin coating the colorant, where the polymer resin is prepared by polymerizing a polymer resin-forming composition including two or more polymerizable unsaturated monomers, and the content ratio of the two or more polymerizable unsaturated monomers is controlled to obtain a glass transition temperature of the polymer resin of &#x2212;15 to 75&#xb0; C. An ink composition including an encapsulated colorant, and an ink set comprising two or more types of the ink composition. The encapsulated colorant may have different glass transition temperatures to have a utility of high optical density when printing text, and high gloss when printing images.

Encapsulated colorant and ink composition including the same

Provided are an encapsulated colorant, a method of preparing the same, and an ink composition including the encapsulated colorant.
